Police have found bomb-making materials in the home of the man behind a sniper-style attack that killed five officers in Dallas, who has been identified as an Army veteran and "loner" driven to "kill white officers". "Every day, Denver's police officers place themselves in the street to protect those involved and the property around them".
Dallas Police Chief David Brown said the suspect was killed after negotiations with him broke down and he began exchanging gunfire with police. A sense of urgency was heightened when officers were ambushed Friday in Tennessee, Georgia and Missouri.
Five police officers were shot and killed and seven more injured when Johnson, in an elevated position, opened fire in the city's downtown area.
"It seems as though the sole suspect now has received his justice", Abbott said on Friday.
In a profile with the Dallas Morning News, which described him as a "private man" who is "introspective and intense", Brown Sr. wrestled with whether his brother's death affected his professional life. A photo on Facebook showed Johnson wearing a dashiki - his raised, clinched fist over the words "Black Power".
The city has long made efforts to mend the rift between law enforcement and its black community.
Police questioned two other men and a woman after the shooting, but they have been released, Rawlings said.
Some of the officers targeted were traffic police and were not wearing Kevlar body armour as they wanted to avoid presenting an aggressive posture at what was supposed to be a peaceful protest.
And he raises an interesting question: Would the police response have garnered as much attention if they had used a more traditional means of killing a violent suspect?
And in Tennessee, a man accused of shooting indiscriminately at passing cars and police on a highway told investigators he was angry about police violence against African-Americans, authorities said. Officers crouched beside vehicles, armored SWAT team vehicles arrived and a helicopter hovered overhead. He told police that he was not associated with the movement, but let's see the public try to separate the two. That, too, was captured on a cellphone video. "Tap, tap, pause", he said. "Can we as citizens speak against the actions of a relatively few officers who blemish the reputation of their high calling, and at the same time support and defend the 99 percent who do their jobs professionally, honestly?"
"This was a mobile shooter that had written manifestos on how to shoot and move", Rawlings said.
Groups that he "liked" include the New Black Panther Party (NBPP) and the Nation of Islam, both known for expressing virulently anti-Semitic and anti-white views, the SPLC said in a statement. "And that's what I learned from this. One of the things it can do is put our police officers in harm's way, and we have to be very careful about doing that".
Outside the police sub-station in South San Jose on Friday, Chief Eddie Garcia took a moment to reflect on the events of Dallas.
"There's nothing you can do about sniper attacks, nothing you can do about a man who walks into a coffee shop intent on killing cops", Troyer said Friday.
"As you can imagine, our hearts are broken", DART wrote in a statement.
"She's got four boys who she just wants to be able to be peacefully out here in the world", Williams said of Taylor's sons, ages 12, 13, 15 and 17. In Minnesota, where Castile was shot, hundreds of protesters marched in the rain from a vigil to the governor's official residence.
In the aftermath, President Barack Obama issued an executive order scaling back the program.
Speaking from Warsaw, Poland, where he was meeting with leaders of the European Union and attending a North Atlantic Treaty Organisation summit, the president asked all Americans to pray for the fallen officers and their families. He called them "vicious, calculated and despicable".
