Through the 1033 program, law enforcement agencies may obtain unmanned ground vehicles, explosive ordnance disposal robots (bomb robots) and multiple police bots, such as the iRobot Packbot 510s and the MarcBot.
As in many cities around the country, Black Lives Matter held a demonstration in Dallas to protest the police shootings of two more black men, Alton Sterling of Louisiana and Philando Castile of Minnesota. During the demonstration, Micah Xavier Johnson, an Army veteran who served in Afghanistan, mounted his own personal, deadly protest by shooting police officers guarding the nonviolent rally. Five officers were killed and seven wounded.
After negotiating for some time with Johnson, who was holed up in a community college parking garage, police sent in a robot armed with explosives and killed him. Dallas police chief David Brown said, "We saw no other option but to use our bomb robot and place a device on its extension for it to detonate where the subject was," adding, "Other options would have exposed our officers to grave danger."
The legal question is whether the officers reasonably believed Johnson posed an imminent threat of death or great bodily injury to them at the time they deployed the robot to kill him.
Johnson was apparently isolated in the garage, posing no immediate threat. If the officers could attach explosives to the robot, they could have affixed a tear gas canister to the robot instead, to force Johnson out of the garage. Indeed, police in Albuquerque used a robot in 2014 to "deploy chemical munitions," which compelled the surrender of an armed suspect barricaded in a motel room.
But the Dallas police chose to execute Johnson with their killer robot. This was an unlawful use of force and a violation of due process.
Comment: It's a vicious cycle. The more military-style equipment police forces have access to, the more their training and tactics will revolve around this equipment. Why bother negotiating with a suspect when they can just be murdered by remote control?
