The Dallas police killed the shooter by sending in a "bomb robot" with a bomb attached - and setting off the bomb.
Technology marches on.
I think this would have violated one of Asimov's Three Laws of Robotics. Particlularly number one: "A robot may not injure a human being or, through inaction, allow a human being to come to harm."
But those were laws for robots with "positronic" brains - robots who actually had the ability to understand what they were doing. This wasn't that sort of robot at all. This was basically a remote controlled device.
When you're shooting it out with the cops
And all the action stops
So they can send you a bot...
Will it be friendly? I think not.
