The violent ambush that killed five Dallas police officers and wounded seven more could have been a lot worse, the city's police chief says.
Dallas Chief of Police David Brown told CNN Sunday that the slain gunman told police negotiators he wanted to "kill white people, especially white officers."
Bomb making materials and a journal were found at Johnson's home during a search Friday.
"The material were such that it was large enough to have devastating effects throughout our city and our North Texas area," Brown said.
Micah Xavier Johnson, 25, was killed by police in the deadly attack Thursday night during a protest against police killings of African American men.
Since the shooting deaths of two black men by white police officers over two days last week, protests have been held across the country. Scores of demonstrators have been arrested, with one flash point being the southern city of Baton Rouge, Louisiana, where DeRay McKesson, one of the most prominent activists linked to the police reform protest movement Black Lives Matter, live streamed his own arrest.
Police defended his arrest as a matter of public safety, but demonstrators told U.S. news outlets they believe McKesson was targeted.
McKesson was freed on bond Sunday afternoon after being charged with obstructing a highway. "I remain disappointed in the Baton Rouge police, who continue to provoke protesters for peacefully protesting. There's a lot of work to be done, with this police department specifically,'' he said.
But Louisiana Governor John Bel Edwards disagreed with McKesson's assessment. The governor told a news conference Sunday that he is proud of the state's law enforcement officers, calling their response to the protests "moderate."
In the northern city of St. Paul, Minnesota, where a second man, Philando Castile, was shot to death last week by a policeman after a traffic stop for a broken tail light, hundreds of protesters hurled firecrackers, rocks and bottles at police on Saturday.
The heavily armed officers used smoke grenades and pepper spray to break up the demonstration, with about 100 arrests. Authorities said 27 police officers were injured in the clashes.
