Are we prepared for more killer police robots? Noel Sharkey

When a police robot is used to kill, one has to ask if we are at a tipping point. The dangerous events in Dallas, in which 12 policemen were shot, made it seem permissible to repurpose a robot to apply lethal force. When an armed suspect refused to surrender, a Remotec robot armed with plastic explosives was dispatched to kill him. This wasn't Robocop and it didn't operate autonomously. It was a bomb disposal robot remotely controlled by police officers.
