Extrajudicial robot executions were on the agenda:

"The back-and-forth between the Oakland Police Department and a civilian oversight body concluded with the police relinquishing their push for official language that would have allowed them to kill humans with robots under certain circumstances. It was a concession to the civilian committee, which pushed to bar arming robots with firearms — but a concession only for the time being. The department said it will continue to pursue lethal options."

Specifically, the Oakland police expressed interest in potentially using for this purpose the "gun-shaped" "percussion actuated nonelectric disruptor" that shoots blank shotgun shells and pressurized water – described imaginatively as "a shotgun barrel secured to an 800-pound Roomba on tank treads."
