Bomb Robots: What Makes Killing In Dallas Different And What Happens Next?

""Given how many police [departments] have robots and given how versatile they are and the various uses to which they've been put, including in hostage situations, I think we'll find that there have been other examples of this," says Ryan Calo, a professor at the University of Washington School of Law who studies robotics and cyberlaw. "As far as I know, this is a first time that they've used a robot to intentionally kill someone."

The effort to develop clear policies may result in a patchwork of local regulations similar to those for drones and body cameras, says Elizabeth Joh, law professor at the University of California, Davis. Plus, she says, it raises new questions about when lethal force is justified or deemed excessive in the world of remote-controlled robots."
