Should the Police Have Robot Suicide-Bombers?

This is a guest post. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE. Last week, the Dallas police killed a suspected gunman with a bomb-delivering robot. It was a desperate measure for desperate times: five law enforcement officers were killed and several more wounded before the shooter was finally cornered. Of course, the shooter needed to be stopped; preventing further murder and mayhem is always a priority. But the method, a robot bomb, was so unorthodox that it raises many ethical and policy questions, if not also legal ones.
