On July 7, 2016,Micah Xavier Johnson ambushed and shot police officers inDallas,Texas, killing five, injuring nine others, and wounding two civilians. Johnson, a 25-year-oldArmy ReserveAfghan War veteran, was angry over whitepolice shootings of black men. He shot the officers at the end of a protest against the recent killings by police ofAlton Sterling inBaton Rouge, Louisiana, andPhilando Castile inFalcon Heights, Minnesota.
Johnson fled to a building on the campus ofEl Centro College, where police killed him several hours later with abomb attached to a remote-controlledbomb disposal robot. It was the first timeU.S. law enforcement used arobot to kill a suspect.[8]
The shooting was the deadliest incident for U.S. law enforcement since theSeptember 11 attacks, surpassingtwo related March 2009 shootings inOakland, California, anda November 2009 ambush shooting inLakewood, Washington, each of which killed four police officers and the gunmen. It was the second-deadliest targeted attack of U.S. law enforcement officers in history; and the largest since theYoung Brothers massacre of 1932 killed six officers in Missouri.
Approximately one year before the shooting, a different attack was perpetrated against theDallas Police Department (DPD) whichThe New York Times likened to the 2016 shooting, comparing their outcomes and the armament of the perpetrators. Several officers were involved in both incidents.[9]
On 13 June 2015 at approximately 12:30 a.m., 35-year-old James Lance Boulware (October 26, 1979 – June 13, 2015) parked an armored van in front of DPD headquarters, which is located in theCedars neighborhood.[9] There, he opened fire using what appeared to be a semi-automatic rifle.[10] When police officers responded, Boulware rammed a Dallas Police patrol car and began shooting at officers from inside the van, striking the squad cars. He then fled in the van to nearbyHutchins, Texas (10 miles (16 km) south of Dallas), where he stopped in the parking lot of aJack in the Box franchise. He remained in the van as a standoff with police ensued.[11] Further gunfire was exchanged with the police while a perimeter was set up around the van, and a SWAT team was called in.[12]
The driver identified himself to police as James Boulware, and claimed that the police had taken his son, accusing him of "being a terrorist". He then cut off communication with officers after making increasingly agitated and angry rants against police. The driver then threatened to blow the police up. The standoff continued as SWAT officers used a.50-caliber rifle to disable theengine block of the armored van.[12][13] The standoff ended when a sniper fired additional rounds into the vehicle, killing the driver.[14]
Police subsequently sent in robots that usedwater charges in an attempt to make entry into the vehicle, which succeeded in breaching thewindshield. Police were then able to verify that the suspect was the only person in the vehicle, and that he was dead.[15] Police robots also used water charges to disable two sets of pipe bombs found in the van. Due to concerns that the van, which was identified as a purpose-built "Zombie Apocalypse Assault Vehicle and Troop Transport" with gun ports and armor-plated windows, was booby-trapped with explosives, police then destroyed the van in a controlled explosion.[14] No police officers or civilians were injured in the incident.[16] Four suspicious bags were found at the police headquarters, one of which containedpipe bombs.[11] Another bag exploded while being moved by a police bomb disposal robot, and a third bag found under a police vehicle was detonated by an explosive ordnance disposal team. At 6:19 a.m., the headquarters building was confirmed clear of all explosives.[12]
Dallas officers initially stated that up to four suspects were involved in the attack on their headquarters, but later said they believed only one person was involved and the reports of multiple suspects had resulted from him changing positions during the attack.[12] The only clearly identified suspect communicating with police gave his name as James Boulware.[17] News reports confirmed that Boulware was arrested inParis, Texas, in 2013 after a report of family violence, and several firearms he owned were also confiscated. Boulware's family members then reported to authorities that they were concerned that he might go on a shooting spree after he threatened to kill all the adult members of his family and to shoot up some churches and schools.[18] Boulware later made threats against a judge in his child custody case after he and the mother of his eleven-year-old son lost custody of their son to Boulware's mother, on the grounds that they were unfit for sole custody of the child.[19]
On July 7, 2016, a protest organized by the took place in Dallas in response to the killings of two men,Alton Sterling andPhilando Castile, by police officers in Louisiana and Minnesota, respectively, days before.[20] The Dallas protest was one of several held across the United States on the night of July 7.[21] Around 800 protesters were involved, and around 100 police officers were assigned to monitor the event.[6][22] About 20 to 30open-carrygun rights activists joined the protest march, some wearinggas masks,bulletproof vests, andfatigues, according to Dallas Police ChiefDavid Brown.[23][24][25]

Most of the events happened in the streets and buildings aroundEl Centro College, which forms a city block composed of multiple buildings. The block is bordered by Main Street on the south where the protest march was taking place; Lamar Street (now Botham Jean Blvd.) to the east from where Johnson initiated the shooting spree; and Elm Street to the north where Johnson eventually entered the college.[26]
Around 8:58 p.m. Johnson parked his SUV sideways on Lamar Street, in front of the east entrance to the college, at Building A, and left the vehicle hazard lights blinking.[26][27] At the time, the street had been cleared out in anticipation of the protest.[27] Taking cover at street level, he began shooting at groups of police and protesters who were gathered on Main Street.[3][28] Johnson was believed to have talked to three of the officers he shot before he first opened fire.[27]
Three officers were killed in the initial gunfire, while at least three others and a civilian were injured.[29] Eleven officers fired back.[30] During the shooting, officers, unaware where the shots were coming from, scrambled to block intersections and were exposed to gunfire as a result.[31]
Immediately afterwards, Johnson made his way north on Lamar Street, encountering Officer Brent Thompson along the way.[29] A civilian recorded video of the encounter from his hotel balcony on Lamar Street. The video showed Johnson, clad in tactical clothing and armed with a rifle, loading his rifle and firing indiscriminately to draw officers near his position. When Thompson approached a corner, Johnson engaged him in a gunfight, forcing Thompson to take cover behind a concrete pillar. Johnson fired towards one side of the pillar, then ran over to the other side of the pillar to flank Thompson and shot him multiple times from behind, killing him.[32]
Johnson, injured during the firefight, attempted to enter the Lamar Street entrance of the college by shooting out the glass door but was unable to make his way in.[26] He wounded two campus police officers who were near the doorway inside the building. Corporal Bryan Shaw was shot in the stomach underneath hisbulletproof vest, while Officer John Abbott was hit by flying glass in the legs.[33] Johnson then made his way to Elm Street where he shot out another glass door and entered the college unseen; he then made his way to Building B.[34] Hearing the shattering glass, one of the injured campus officers, Corporal Shaw, made his way through the building and discovered a trail of blood leading to a stairwell. Accompanied by another police officer, Shaw entered the stairwell and was met with a hail of gunfire coming from above. Unable to see Johnson, he held his fire and retreated with the other officer.[26][35]
Afterwards, Johnson made his way along a mezzanine between the school's second-floor dining area and third-floor library, but came onto a dead end of windows facing down onto Elm Street. He shot out multiple windows and fired repeatedly at officers on Elm Street. He hit Michael Smith, a police officer standing in front of a7-Eleven, killing him and shattering the store-front glass. Officers began entering the college, sealing escape routes from the building, and evacuating students and teachers in the building, including those on a floor above Johnson, through a different stairwell.[26][27][29]
Approaching Johnson on the second floor near the library,[34] officers found him secured behind a corner firing intermittently.[36] He was in an area filled with offices and the school's computer servers, with only two doors leading to where he was positioned, and a hallway about 30 feet (9.1 m) long separating him fromSWAT members.[27][34] At least 200 gunshots were believed to have been fired by Johnson and SWAT officers in that area during the standoff.[34]
Body camera video released in July 2021 pursuant to an open records request shows Sergeant Larry Gordon, a SWAT negotiator at the time, and other officers attempting for several hours to negotiate with Johnson. Officers interviewed by WFAA later said that they had sought to negotiate with Johnson because he was too heavily armed for the officers to risk charging him, but that they were under pressure and could not wait indefinitely because Johnson could pop out from behind a corner at any time to shoot an officer.[37] The body camera footage shows Senior Corporal Matt Banes expressing concern that the bullets Johnson fired on the second floor were easily penetrating thedrywall, making it impossible for the negotiators to find safe cover, and posing a risk to any students who might have remained in the building.[37][38]
Johnson shouted "black supremacy! Black liberation!" and began firing on police officers when they initially cornered him in the hallway. As the officers began asking Johnson questions, Johnson said he would speak to black police officers only and repeatedly referred to himself as "X". When the negotiator, Sgt. Gordon, told Johnson that he was black, Johnson initially responded, "No way." Johnson told Sgt. Gordon that he served overseas in the military. At one point, as negotiations deteriorated, Johnson told Sgt. Gordon, "The talking is over. It's time for a revolution, brother. If you are my brother, turn your weapon on those behind you."[37][38]
Johnson said that he had acted alone and was not part of any group. According to Chief Brown, Johnson appeareddelusional during his standoff; "We had negotiated with him for about two hours, and he just basically lied to us, playing games, laughing at us, singing, asking how many did he get and that he wanted to kill some more." However, Sgt. Gordon indicated in an interview that the shooter "wasn't delusional" and that "he was very lucid, seemed to be very sane and very in control".[37][38]
Johnson repeatedly taunted police by goading them into the hallway and claiming to have planted bombs throughout the city.[28][39] Later searches of downtown Dallas found no evidence of explosives.[20] After several hours of negotiations, police determined that Johnson could not be persuaded to surrender[40] and that they could not "wait him out" any longer because he might charge officers in the narrow hallway at any moment, as he had done several times earlier. So, the team began considering several tactical plans to end the standoff.[37]
Sr. Cpl. Banes said they considered using a .50 caliber rifle to fire at the shooter, which had been successful in the 2015 attack approximately one year earlier. However, in that case, the suspect had driven an armored truck into police headquarters and remained inside the vehicle. Johnson was holed up inside a populated college with thin Sheetrock walls, so the tactical team deemed that approach too dangerous. They also considered rappelling down the building or attacking Johnson through the ceiling after opening it with explosives. Both options were ruled out due to the risks they might pose to the officers who would carry it out.[37]
Senior Corporal Jeremy Borchardt and others ultimately arrived at the idea to use abomb disposalremote control vehicle armed with about 1 pound (0.45 kilograms) ofC-4 explosive. The plan was to move the robot to a point against a wall facing Johnson and then detonate the explosives.[41][42][43] The device exploded as intended at approximately 2:30 a.m., killing Johnson immediately.[44] It was the first time that explosives strapped to a robot had been used in American domestic law enforcement.[37] Although its arm sustained damage in the blast, the robot was still functional.[45]
In the aftermath, police investigated Johnson's body and equipment. He was found lying next to a rifle, two handguns, additional rifle magazines, and a bag filled with supplies.[37] Police had initially located Johnson within the college by following a trail of blood he had left behind as he climbed to the second floor, bleeding from a wound he had sustained on Lamar Street.[26] After the standoff, investigators discovered that Johnson had scrawled the letters "RB" and other messages in his own blood while making his way up a stairwell.[46][47] Police investigated the markings made by Johnson, but did not conclusively determine if they had any special meaning.[46][47][48]
Asked about the remarks Johnson made during the negotiation, Sgt. Gordon later reflected, "I think he was angry...and he felt powerless, I think. And that's why I think he took the rifle and took it upon himself to attack us. Because he felt powerless, and he wanted to die to show...because he says he's doing this for his people...And I think the hook that I had with him was that I was an African-American male."[37]
Five officers were killed; nine other officers and two civilians were injured.[33][49][50]
Most of the victims were shot during the protests, and at least one other during a shootout.[51][52] The dead comprised four DPD officers and oneDallas Area Rapid Transit (DART) officer.[20] Four of the injured officers were from DPD, three were from DART,[44] and two were fromEl Centro College.[33][53][54] Seven of the injured officers were treated atParkland Memorial Hospital.[55] Two officers underwent surgery.[56] One civilian was shot in the back of the leg, breaking her tibia.[57]
The officers killed were identified as:
This was the deadliest single incident for law enforcement officers in the United States since theSeptember 11 attacks,[1] surpassing two 2009 shootings inLakewood, Washington, andOakland, California, which each left four officers dead.[68][69]
Micah Xavier Johnson was born inMagee, Mississippi,[70] on July 2, 1991, and he was raised inMesquite, Texas.[20][65][71][72] He once described his childhood as "stressful" during aVA visit on August 15, 2014, but further details were redacted on the visit report.[73] When he was four, his parents divorced.[72][74]
Johnson transferred intoJohn Horn High School when he was 17 and participated in itsJunior Reserve Officers' Training Corps program, according to theMesquite Independent School District.[72][74] He struggled academically, graduating in 2009 with a 1.98grade-point average and a ranking of 430 out of 453 students in his class.[72][75][76]
In the spring of 2011, he enrolled in four classes atRichland College, but never completed any of them.[77] Investigators believed that Johnson had access toEl Centro College through his enrollment at Richland, citing his pre-planned and coordinated movements throughout Building B.[27]
Immediately after high school,[78] Johnson enlisted in theU.S. Army Reserve and served from March 2009 to April 2015 as a12Wcarpentry andmasonry specialist.[79] He completedbasic training, which required qualification on handling of anM16 rifle orM4 carbine, basic rifles for U.S. military personnel.[80] According to Justin Garner, a high-school friend and classmate who later served alongside Johnson in the same unit, Johnson lacked proficiency in certain required technical skills, such as marksmanship.[72]
Johnson wasactivated at the rank ofprivate first class in September 2013 in support of theWar in Afghanistan, where he was deployed from November 2013 to July 2014[3][75][81] with the420th Engineer Brigade.[82]
People who knew Johnson during his time in the Army described him as openly religious and often socializing with white soldiers.[77] Asquad leader, who trained Johnson in tactical maneuvers and protection in 2009 and 2010, described him as "klutzy", "goofy sometimes", and "a nice guy", but also quiet and unmotivated.[83][84]
Documents released by the Army on July 29 detailed early signs of disturbing behavior being exhibited by him, but specific details were redacted.[85] They also said that while Johnson was sociable, he was generally described by soldiers as aloner who sometimes ate his lunch in a vehicle alone while the rest of his unit ate outside together.[86]
On May 1, 2014,[87] during his deployment, Johnson was accused ofsexual harassment by a female soldier, who sought aprotective order against him and said that he needed mental health counseling.[72][88][89][90] The accusation was made after the soldier reported four pairs of women's underwear missing from her laundry bag. A "health and welfare inspection" of soldiers' rooms found one pair in Johnson's quarters, while a soldier discovered the remaining three in Johnson's pocket. Upon being confronted about it, Johnson fled with the undergarments and attempted to dispose of them in a nearby dumpster. He then lied that a female civilian acquaintance gave the underwear to him, but the female soldier confirmed that they were in fact hers.[85][86][91][92]
The female soldier told investigators that she and Johnson had beenplatonic friends for five years, but had stopped talking to each other. She described their relationship as being tumultuous and involving fights and disagreements. She specifically recalled one incident where Johnson punched out a car window over her leaving for college and severed an artery, then forced her to bring him to a hospital for treatment. However, Johnson claimed that he punched out the window when the soldier missed a movie they planned to see together, and added that he had been under stress from his job and turbulent home life at the time.[87][93][94][95]
According to the soldier, Johnson asked her for a pair of her underwear before the May 1 incident, but she declined. Also, during aFacebook conversation with her, Johnson mentioned "tying her down and having her face down on the bed" but then claimed the statement was a joke. Though she told him that rape was "never a joke" and to stop contacting her, the soldier did not report him for harassment at the time because she was used to that kind of rhetoric.[87][96] Though the May 1 incident did not meet the Army's criteria for sexual harassment, investigators found that Johnson's sexually suggestive comments to the female soldier met said criteria.[85][86][91][92]
Following the inspection, he was disarmed under the recommendation of his platoon sergeant, who felt he posed a threat. Another Army official later described the action as unusual, as Johnson did not appear to be visibly agitated or a threat to himself or others at the time.[93][94] Johnson was then placed under 24-hour escort, which was reportedly a shameful and ostracizing experience,[72] before being temporarily moved toBagram Airfield on May 3, but he did not have enough time to pack all of his belongings. While soldiers were emptying Johnson's quarters and packing his belongings for him on May 14, they discovered an unauthorized single M430I High Explosive Dual Purpose40mm grenade, a.50-caliber round, and another soldier's prescription medication in his sleeping bag.[85][86][87][92]
Later, the Army sent Johnson back to the U.S., and according to themilitary lawyer who represented Johnson at the time, the Army initiated proceedings to give Johnson an "other than honorable" discharge. The lawyer claimed this was "highly unusual" because written reprimands are usually issued before more drastic steps are taken, and also because the decision was allegedly based on a single sexual harassment allegation. The lawyer was evidently unaware of the grenade and other contraband discovered in Johnson's possession shortly before he was repatriated to the United States from Afghanistan as well as other factors in Johnson's possibly redacted record.[78][88][90] On the advice of his attorney, Johnson waived his right to a hearing in exchange for a more favorablegeneral discharge under honorable conditions.[88][97] He washonorably discharged in September 2014, apparently as a result of an Army error.[89] Johnson remained in theIndividual Ready Reserve (IRR), meaning he could be recalled into the Army if needed, and was part of the IRR at the time of his death.[75][93]
Johnson received theAfghanistan Campaign Medal withcampaign star,Army Achievement Medal,Global War on Terrorism Service Medal,Armed Forces Reserve Medal, andNATO Medal for his tour of duty in Afghanistan.[40][82]
Some of Johnson's fellow soldiers criticized the Army's handling of the case.[72][97]
Chief Brown said that Johnson, who wasblack, was upset about recentpolice shootings of black men and "stated he wanted to kill white people, especially officers."[6][7] A friend and former coworker of Johnson's described him as "always [being] distrustful of the police."[74] Another former coworker said he seemed "very affected" by recent police shootings of black men.[77] A friend said that Johnson hadanger management problems and would repeatedly watch videos of the 1991 beating ofRodney King by police officers.[98] Brown said that Johnson had told police negotiators that he was upset about Black Lives Matter. Police said they had found no direct ties between Johnson andBlack Lives Matter protesters, and believed the suspect had been planning an attack for some time and acted on his own.[99][79]
An investigation into his online activities uncovered his interest inBlack nationalist groups.[88] TheSouthern Poverty Law Center (SPLC), and news outlets reported that Johnson "liked" the Facebook pages of Black nationalist organizations such as theNew Black Panther Party (NBPP),Nation of Islam, andBlack Riders Liberation Party, three groups which arelisted by the SPLC ashate groups.[100] On Facebook, Johnson posted an angry and "disjointed" post against white people on July 2, several days before the attack.[101]
NBPP headQuanell X said after the shooting that Johnson had been a member of the NBPP'sHouston chapter for about six months, several years before.[102] Quanell X added that Johnson had been "asked to leave" the group for violating the organization's "chain of command" and espousing dangerous rhetoric, such as asking the NBPP why they had not purchased more weapons and ammunition, and expressing his desire to harm black church preachers because he believed they were more interested in money than God.[103][104][105] Following the shooting, a national NBPP leader distanced the group from Johnson, saying that he "was not a member of" the party.[104]
Further investigation into his digital footprint showed that Johnson visited the sites ofMarxist Leninist groups associated with "Revolutionary Black Nationalism", a left wing counterpart of right wing "black nationalism". He also posted multiple BPP posters and other forms of far-left propaganda some of which called for a "class war", though this is contradictory to other posts and likes he made. Johnson "liked" the Facebook page of the African American Defense League, whose leader, Mauricelm-Lei Millere, called for the murders of police officers across the U.S. following the 2014murder of Laquan McDonald.[88][104] In response to the police killing ofAlton Sterling, the organization had "posted a message earlier in the week encouraging violence against police".[89]
Johnson's Facebook profile photo depicted Johnson raising his arm in aBlack Powersalute, along with images of a Black Power symbol anda flag associated with thePan-Africanism movement.[88][101] These symbols have long represented Black empowerment, but have also been co-opted by reactionary groups with bigoted views.[88]
Conversely, people familiar with Johnson during his military service believed he may have been severely stressed with serving in a combat zone. They also said he had little interest in the topics of racial injustice and thekilling of Trayvon Martin that occurred at the time.[77] In an interview, Johnson's parents said that he was once extroverted and patriotic, and wanted to become a police officer. Following his discharge from the Army, they described him as disillusioned, reclusive, and resentful of the U.S. government; and believed he had been disappointed by his experience in the military.[90][106] According to a soldier, Johnson had a small breakdown after he began losing his friends in the Army after details of the sexual harassment accusation were released.[97]
According to an employment application made by Johnson seven months before his death, he worked in aJimmy John's sandwich shop in north Dallas beginning in 2010, and took a position as aquality assurance worker at aGarland, Texas, truck plant in 2012.[75] At the time of his death, Johnson was working as an in-home caregiver for his mentally disabled adult brother. Both men lived with their mother in her home.[107][75]
Johnson had no criminal record in Texas.[20] However, theMesquite Police Department documented an encounter with him in January 2011. According to the report, Johnson walked into their police station "visibly upset and...bouncing from side to side." He told an officer that a female friend had lied to him and that he had nowhere else to go. He also declined mental health treatment and claimed he was not a threat to himself or others. Johnson was eventually picked up from the station by a friend from hisArmy Reserve unit.[86]
TheVeterans Health Administration released documents in August 2016 showing that Johnson had symptoms forpost-traumatic stress disorder (PTSD) following his return from Afghanistan. He was not formally diagnosed with the condition, and doctors concluded that he presented no serious risk to himself or others. Johnson had sought treatment for anxiety, depression, and hallucinations, once telling doctors that he had experienced nightmares after witnessing fellow soldiers dying in explosions. Johnson also said that he would hear voices and mortars exploding; and that after returning to the U.S., he would be paranoid, suffer from lower back pain, and experience panic attacks a few times per week. For the latter condition, he recalled one incident at aWal-Mart that required a police response. For his conditions, Johnson was prescribed several medications, including a muscle relaxant, an antidepressant, and anti-anxiety and sleep medication.[73]
Chief Brown said that while Johnson had been planning the shooting before the deaths of Sterling and Philando Castile, both incidents served as the trigger to commit the shooting and that he saw the Dallas protest as "an opportunity" to attack police officers.[108] Johnson had offered to work security at an anti-Donald Trump rally led by Dallas civil rights activist Reverend Peter Johnson on June 16, but he insisted on bringing a gun, so the reverend declined.[109]
According to police and a neighbor, Johnson practiced military exercises in his backyard.[110][111] In 2014, Johnson received training and instruction at a private self-defense school that teaches tactics such as "shooting on the move" (i.e., quickly firing, then changing position and resuming gunfire).[112] The tactic was designed to keep a gunman's location uncertain and create the impression of multiple shooters.[113] Although the school's website does mention such training as being offered, Justin Everman, the founder of the school, stated that Johnson only took self-defense courses two years ago.[114] Investigators believed that he began amassing his arsenal around the same time, stockpiling guns and gathering chemicals and electronic devices andPVC piping needed to build explosives.[80][115]

There were conflicting reports on the type ofsemi-automatic rifle that Johnson used during the shooting.[116]Clay Jenkins, the Dallas County chief executive and the director of homeland security and emergency management, said Johnson used anSKS.[110][116] News reports, all citing unnamed officials familiar with the investigation, said Johnson used anIzhmash-Saiga5.45mm rifle, which is a variation on theAK-74.[116][117][118][119][120]
The New York Daily News interviewed a man who sold Johnson a semiautomaticAK-74 pattern rifle in November 2014. The man said he sold Johnson the rifle and made the deal in aTarget parking lot. When the man asked theATF if his weapon played a part in the shooting, the ATF agent who responded said, "All we can say is it was recovered. We're just finding out everything we can."[121]
In addition to the rifle, Johnson carried at least onehandgun with ahigh-capacity magazine during the attack.[110] CNN, citing an unnamed official, reported that two handguns were recovered, one aGlock 19 Gen4 pistol and the other aFraser .25-caliber.[118]
The FBI reported that Johnson wore ballisticbody armor withhard armor plates during the shooting.[46]
Johnson's family home was searched by authorities the day after the shooting.[122] Bomb-making materials, ballistic vests, two rifles, ammunition, and a "personal journal of combat tactics" containing "instruction on shooting techniques and tactical movements" were recovered from the home by detectives.[44][43][119][123] Chief Brown reported that the journal included "quite a bit of rambling ... that's hard to decipher."[46]
Chief Brown said that recovered evidence pointed to Johnson practicing detonations and having enough explosive material to cause "devastating effects" throughout Dallas and theNorth Texas area.[31] However, the latter claim was contradicted on July 18 by two officials familiar with the investigation, who both said small amounts ofTannerite, abinary explosive used to make explosive targets for gun ranges, andacetone, an accelerant in explosives, were recovered from the home.[124]
Investigators interviewed 300 witnesses and officers after the shooting.[125] Investigators examined Johnson's laptop, journal, and cell phone, along with 170 hours ofbody camera footage.[31][125] However, there were concerns about the resolution quality of some of the 90 cameras installed in downtown Dallas, which could have recorded parts of the shooting essential to the investigation. The cameras were part of a multimillion-dollar downtown surveillance system implemented to reduce crime in the area.[126] The DPD planned to release surveillance footage of the shooting on August 29, but held off, saying the release would interfere with its investigation.[127]
Officials initially said two or more snipers carried out the shooting, with the confusion later attributed to ricocheting bullets and the echoes of gunshots. They later said that Johnson appears to have been the lone gunman, with all of the gunshots traced back to him. Three other people were taken into custody by police, "but officials have not said what roles they may have played."[7][29][128][129] These three included two people seen carryingcamouflage bags and leaving the shooting scene on Lamar Street. They were both stopped and detained after a six-mile chase.[130] The detained persons were all later determined to be fleeing protesters who were either armed or carrying ammunition gear.[123] However, police announced on July 9 that they were continuing to investigate whether Johnson acted alone or conspired with others in planning the shooting.[131] Investigators obtained asearch warrant to look for phone numbers connected to Johnson.[119]
One of the people taken into custody by police had attended the protest wearing a camouflage T-shirt and openly carrying an unloadedAR-15 rifle.[132] Shortly after the shooting, the DPD tweeted a photo of the man describing him as one of their suspects and asked the public's help in finding him.[133] The police-released image of the suspect was widely shared on social media and broadcast on national television.[134] The suspect turned himself in and was subsequently released after questioning without charge.[135]
The then-president of the Dallas Police Association, Mike Mata, stated that due to the criticism ofmilitarization of police, someone within the DPD's chain of command ordered the officers assigned to the protest to not wearmilitary-style bulletproof vests because they did not want the officers to look too "militaristic, aggressive" and instead to wear standard issuekevlar vests, which were not able to protect against the rifle rounds Johnson fired. For the same reasons, officers were not able to arm themselves with long guns, such asAR-15s. Mata was interviewed by the local news stationKDFW and said, "[A] lot of those shots, and a lot of those wounds… werechest shots,lower abdomen wound shots, and those heavy vests would have covered them".[136]
On July 13,Pentagon officials announced that theU.S. Army had launched an internal review into Johnson's military service. The review was initiated after questions were raised about the appropriateness of his honorable discharge despite the sexual harassment allegations made against him, and the fact that the Army had been highly considering an "other than honorable discharge" for Johnson.[76][78]
During the investigation, the Army uncovered an incomplete amount of information regarding the sexual harassment allegations. The following day, another review was initiated by the Army'sCriminal Investigation Command, to determine if a full investigation was made into the allegations. An Army official echoed a statement made by the lawyer who represented Johnson, saying that Johnson's honorable discharge may have been the result of an administrative error. The same official added that nothing had been found in Johnson's record that indicated a willingness to commit murder.[137]

Chief Brown said that police efforts to identify the gunman were made more difficult by the presence of up to thirty civiliansopenly carrying rifles during the protest, which is legal in Texas. Brown said, "We're trying as best we can as a law enforcement community to make it work so that citizens can express theirSecond Amendment rights. But it's increasingly challenging when people haveAR-15s slung over their shoulder and they're in a crowd. We don't know who the good guy is versus the bad guy when everyone starts shooting." In an interview after the shooting, Dallas MayorMike Rawlings said that he supported changingstate law to restrict the public carrying of rifles andshotguns so that the police could distinguish between suspects and civilians more easily during crises.[144][145]
Dallas Observer noted several similarities between Johnson andMark Essex, a dischargedU.S. Navy sailor andBlack Panther who committed two attacks against White civilians and police officers on December 31, 1972, and January 7, 1973, inNew Orleans. The attacks left nine people dead, including five police officers.[146]

In November 2016, Enrique Zamarripa, the father of Officer Patrick Zamarripa, one of the murdered police officers, filed a lawsuit againstBlack Lives Matter and 13 other defendants, including theNation of Islam, theNew Black Panther Party, the ReverendAl Sharpton, and individual activists. The lawsuit seeks $550 million in damages and claims that Johnson was acting as an agent for the defendants and alleged that the defendants incited violence and caused the Dallas shooting as a "direct result".[148][149] The mother of the officer, Valerie Zamarripa, distanced herself from her ex-husband's lawsuit, saying that it did not reflect her views, or the views of the foundation set up in her son's name.[149]
Earlier, in September 2016, a Dallas police officer, Sgt. Demetrick Pennie, represented by lawyerLarry Klayman, filed a lawsuit in theU.S. District Court for the Northern District of Texas against 17 people—includingLouis Farrakhan, the Nation of Islam, Sharpton, theNational Action Network, Black Lives Matter,DeRay Mckesson,Malik Zulu Shabazz, the New Black Panther Party,George Soros, PresidentBarack Obama,Eric Holder,Hillary Clinton, andJesse Jackson—blaming them for the attack and seeking damages of over $500 million.[150][151] Klayman has used his nonprofit group Freedom Watch to pursue lawsuits that "further supposed 'far-right' causes" in the past.[152] The lawsuit was seen as "unlikely to be taken too seriously by a judge"[150] and all of Klayman's claims against Mckesson and Black Lives Matter were dismissed or withdrawn.[153] Attorneys for Mckesson have argued that "Klayman should have known his claims were frivolous."[153]
In January 2017, Pennie separately suedTwitter,Facebook, andGoogle in theU.S. District Court for the Northern District of California, claiming that the websites "knowingly and recklessly" allowed terrorist propaganda to be spread on their social networks.[154][155]

This included $86,000 spent by the Dallas County Sheriff's Office, $88,000 spent by the Arlington Police Department, about $705,250 by DPD, and unknown sums by the Irving Police Department and the Dallas Fire-Rescue Department.[156]
Following this shooting andanother in Baton Rouge, Louisiana, that killed three police officers and wounded three others, local law enforcement agencies across the U.S. began re-adjusting response strategies, with more officers being paired up in patrol vehicles.[a] Departments also began to increase security and surveillance at protest events against police.[157]
Within twelve days of the shooting, DPD received 467 job applications, representing a 344% increase from the 136 applications received by the department in June. In the months before the shooting, DPD, along with other police departments across the country, had been struggling to recruit new officers. DPD had to cancel academy classes because there were not enough applicants, and also struggled in retaining officers due to a low salary.[158][159] On August 25, DPD announced their goal of hiring 549 officers by October 2017, though some police and City Council officials called the effort unrealistic due to the department's strict hiring requirements.[160]
The killing of Johnson was the first time in United States history a robot was used by police to kill a suspect.[161] TheRemotec ANDROSMark V-A1,[162] abomb disposalremote control vehicle used by police, was rigged with about 1 pound (0.45 kilograms) ofC-4 explosive.[163][41][164][42][43] The decision to attack Johnson with a robot was made after it was concluded that the heavily armed assailant had secured himself behind a corner at the end of a hallway, with no safe way for police to rush him or reach him with a sniper.[35][36]
There were various reactions to the lethal use of a robot by police.P. W. Singer, a robotics expert at theNew America Foundation, said it was the first instance of which he was aware of a robot being used lethally by police.[165][166][167] Seth Stoughton, an assistant professor of law at theUniversity of South Carolina, said, "This is sort of a new horizon for police technology. Robots have been around for a while, but using them to deliver lethal force raises some new issues."[168]
To this effect, Stoughton said, "I'm not aware of any police department having on hand something that is intended to be used as a weaponized explosive." He believed that the manner in which the police used the robot wasjustified due to Johnson being an imminent threat to police personnel and civilians, stating, "The circumstances that justifylethal force justify lethal force in essentially every form."[168]
Texas GovernorGreg Abbott ordered the director of theTexas Department of Public Safety to offer any assistance to Dallas when requested. He also said, "In times like this we must remember—and emphasize—the importance of uniting as Americans."[169] Texas Lieutenant GovernorDan Patrick attributed the violence to individuals on social media, "former Black Lives Matter protesters", and others with anti-police views,[170] later expressing regret for his statement.[171]

Kalyn Chapman, a model and the first black woman to be namedMiss Alabama, called the perpetrator "amartyr" in aFacebook Live video, stating: "I wasn't surprised by what the shooter did to those cops, and I think a lot of us feel the same way."[185] Chapman subsequently toldCNN that she regretted referring to Johnson as a martyr, stating: "While I detest the killing of those officers and the taking of innocent lives, I did, in a way, I understood what could drive the shooter to do something like that. I don't consider him a hero."[186] Chapman's employer,WPBT, announced that she had been placed onadministrative leave following her comments.[187][188][189]
