Micah Johnson, a disgraced Army vet, is thought to have shot and killed five police officers and injured seven others in Dallas last Thursday. Johnson was killed in turn, hours after being cornered by police in a nearby parking garage. But Johnson didn't fall to police gunfire. He was blown up.
In what appears to be a first, the Dallas police used a Multi-function Agile Remote-Controlled Robot, or MARCbot, to end Johnson's life. The MARCbot, also known as a "bomb robot," was a simple military robot with an explosive attached to its arm, sent to dispatch the suspected Dallas shooter without endangering police officers' lives. But the use of the bomb robot has raised significant issues about the blending of military and police technologies and the delivery of deadly force when dealing with dangerous suspects.
