Robot's role in killing Dallas shooter is a first

Turner was surrounded by City Council members and several police officers, all of them wearing a black stripe across their badges in honor of the Dallas officers slain while protecting protestors, who were demanding an end to police killing young black men who simply reach for their wallets in their waistline pockets.

The attack on the officers - the deadliest day for US law enforcement since the 2001 terrorist attacks - has "stunned" and "outraged" Americans, Ryan said.

"The shots were coming from the roof", one protester told the station.

Meanwhile, back in the U.S., Homeland Security Secretary Jeh Johnson told reporters "there appears to have been one gunman", Micah Xavier Johnson, 25, who had "no known links to or inspiration from any global terrorist organization".

"Because ground robots may allow deadly force to be applied more safely and easily, they raise the danger that they will be overused", Stanley said. While there doesn't appear to be any hard data on the subject, security experts and law enforcement officials said they couldn't recall another time when police have deployed a robot with lethal intent.

The use of force by police against African-Americans in cities from Ferguson, Missouri, to Baltimore and NY has sparked periodic and sometimes violent protests in the past two years and has spawned the Black Lives Matter movement. "We felt that was the safest way to get him and it was".

Police Chief Brown said that a "female who was in the same area" had been taken into custody. It concluded that officers in major gun-owning states were three times likelier to be killed. A Dallas Area Rapid Transit (DART) officer since 2009, Mr. Thompson is the first officer in the department to be killed in the line of duty since it was established in 1989, according to the department.

Some details began to emerge about Johnson.

Burton's opinion was echoed in a tweet Friday from a warfare strategist at the New America Foundation.

His killing was captured on video by a bystander. While photos depict Johnson in his camouflage Army uniform, the cover shot on his Facebook page carries the red, black and green Pan-African flag.

The US military said earlier that Johnson, who had been widely identified by media as the shooter, had served with US forces in Afghanistan from November 2013 to July 2014. USA Today reported Johnson was a private first class with a specialty in carpentry and masonry.

Details on how the shootings unfolded remained unclear. "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".

He said the man told police "there are bombs all over the place in this garage and downtown".

I was struck yesterday by an interview with Michael McClanahan, president of the NAACP in Baton Rouge, who went out of his way to include the modifier. "I didn't know what to do", Hood told reporters on Friday. "If we continue to turn to violence, we are going to continue to see heartache and devastation".

The ambush in Dallas is being called the deadliest day in the nation for law enforcement officials since the September 11, 2001 terrorist attacks.

President Barack Obama called the shootings "vicious, calculated and despicable".

Fargo Deputy Police Chief Joe Anderson said emotions in his department were "across the board" Friday as staff pondered the deaths and injuries inflicted on the Dallas Police Department.

Others, like Dallas Republican Rep. Pete Sessions, said the attack is a tragedy, but not one that calls for congressional intervention.

A study in the American Journal of Public Health suggests USA police officers may have reason for jitters around their well-armed citizenry.

Rep. Johnson, who lives near downtown, worries about what the attack means for the city that has worked to overcome the stigma of the Kennedy assassination and to promote strong relationships between citizens and the police. Seven others were wounded, along with two civilians.

A day earlier, Alton Sterling was shot in Louisiana after being pinned to the pavement by two white officers.

Both major US presidential contenders canceled their campaign events for Friday following the attack.
