The suspected sniper who killed five police officers and wounded two civilians following a peaceful Black Lives Matter march in Dallas was killed when police deployed an explosives-rigged robot into the parking garage where he was holed up.  Police say there were hours of fruitless negotiations before the robot outfitted C4 explosive was sent in. Associated Press said this "appears to be the first time US police have used a robot for lethal purposes. As such, it may represent the latest escalation in the use of remote and semi-autonomous devices by law enforcement." Ironically, the robot was ostensibly procured by the police force for "bomb-disposal" purposes. This apparent first use of a killer robot in domestic policing comes as human rights groups are calling for restrictions on their use in actual warfare.

The deceased suspect, Micah Xavier Johnson, 25, is an Army veteran whose tour of duty in Afghanistan was cut short by a sexual harassment complaint last year.  (Dallas Morning News, The Root, Military.com)
