Dallas Police Believed to Be First to Use Robot Lethally

The Dallas police's use of a robot to kill a man suspected of shooting police officers may have been the first time U.S. law enforcement intentionally used a robot lethally, two security researchers said Friday. Dallas Police Chief David Brown said Friday that officers decided to use a bomb-disposal robot jury-rigged with explosives after negotiating with the suspect for several hours and then exchanging gunfire with him.
