Dallas PD turned robot into IED to get sniper

When Dallas police officers were under fire during a deadly sniper attack last week, it was a nearly 4-foot-tall robot that took out the suspected assailant.
It's believed to be the first time that police have used a robot to kill someone, taking the technology from a passive role, such as capturing images or video of a crime scene, to an active and lethal role.
Police used the robot to try to take out the attacker, Micah Xavier Johnson, 25, of Mesquite, Texas, who ambushed police officers work
