DALLAS — The suspect in the deadly attack on Dallas police taunted authorities during two hours of negotiations, laughing at them, singing and at one point asking how many officers he had shot, the police chief said Sunday.
Micah Johnson, a black Army veteran, insisted on speaking with a black negotiator and wrote in blood on the wall of a parking garage where police cornered and later killed him, David Brown told CNN’s “State of the Union.”
Johnson, who was apparently wounded in a shootout with police, wrote the letters “RB” and other markings, but the meaning was unclear. Investigators are trying to decipher the writing by looking through evidence from Johnson’s suburban Dallas home, Brown said.
The chief defended the decision to kill Johnson with a bomb delivered by remote-controlled robot, saying negotiations went nowhere and that officers could not approach him without putting themselves in danger.
Brown said he became increasingly concerned that “at a split second, he would charge us and take out many more before we would kill him.”
Johnson had practiced military-style drills in his yard and trained at a private self-defense school that teaches special tactics, including “shooting on the move,” a maneuver in which an attacker fires and changes position before firing again.
He received instruction at the Academy of Combative Warrior Arts in the Dallas suburb of Richardson about two years ago, said the school’s founder and chief instructor, Justin J. Everman.
Everman’s statement was corroborated by a police report from May 8, 2015, when someone at a business a short distance away called in a report of several suspicious people in a parked SUV.
The investigating officer closed the case just minutes after arriving at a strip mall. While there, the officer spoke to Johnson, who said he “had just gotten out of a class at a nearby self-defense school.”
Johnson told the officer he was “waiting for his dad to arrive” and pick up his brother. No one else was apparently questioned.
On Friday, Dallas Mayor Mike Rawlings described Johnson as “a mobile shooter” who had written manifestos on how to “shoot and move.”
Authorities have said the gunman kept a journal of combat tactics and had amassed a personal arsenal at his home, including bomb-making materials, rifles and ammunition.
The academy website refers to one of its courses as a “tactical applications program,” or TAP.
“Reality is highly dynamic, you will be drawing your firearm, moving, shooting on the move, fixing malfunctions, etc. all under high levels of stress,” the website says. “Most people never get to train these skills as they are not typically allowed on the static gun range.”
The TAP training includes “shooting from different positions,” “drawing under stress” and “drawing from concealment.” Everman declined to specify which classes Johnson took.
Johnson donned a protective vest and used a military-style semi-automatic rifle for the shootings, which marked the deadliest day for U.S. law enforcement since the Sept. 11, 2001, terrorist attacks.
