Dallas gunman learned tactics at Texas self-defense school
DALLAS (AP) — The gunman who killed five police officers at a protest march 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.
Authorities have said the 25-year-old gunman kept a journal of combat tactics and had amassed a personal arsenal at his home, including bomb-making materials, rifles and ammunition.
"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.
Earlier in the day, President Barack Obama called Johnson a "demented individual" who does not represent black Americans any more than a white man accused of killing blacks at a church in Charleston, South Carolina, represents whites.
The president planned to visit Dallas in a few days and to convene a White House meeting next week with police officers and community and civil rights activists.
Johnson, who donned a protective vest and used a military-style semi-automatic rifle, was killed by a robot-delivered bomb Thursday after the shootings, which marked the deadliest day for U.S. law enforcement since the Sept. 11, 2001, terrorist attacks.
The attack began Thursday evening while hundreds of people were gathered to protest the police killings of Philando Castile, who was fatally shot near St. Paul, Minnesota, and Alton Sterling, who was shot in Louisiana after being pinned to the pavement by two white officers.
After shooting at the Dallas officers, Johnson tried to take refuge in a parking garage and exchanged gunfire with police, authorities said.
