Dallas Shooter Killed By Robot

Dallas police improvised when they decided to use a robot typically deployed to inspect potential bombs to instead deliver one to kill a gunman who had slain five officers at a march against police violence, the city's police chief said on Monday.

The gunman who fatally shot five Dallas law enforcement officers appeared delusional, taunted police during extensive negotiations by singing and "laughing at us" and wrote cryptic messages on a wall with his own blood before he was killed by a bomb-equipped robot, Dallas Police Chief David Brown said Sunday.

When Dallas police used a bomb-carrying robot to kill a sniper, they also kicked off an ethical debate about technology's use as a crime-fighting weapon.
