Have we as a species learned nothing from Robocop?
A Silicon Valley company called Knightscope is currently testing a prototype robot designed to detect and monitor criminal activity, much the way a police officer or a security guard would.
The Knightscope K5 is a five-foot-tall autonomous robot (one presumes that its resemblance to a Dalek is merely coincidental) that roams around your neighborhood, observing and gathering data and trying to predict where and when criminal activity will occur.
It carries no weaponry, but it has a pretty complete sensor package that includes thermal imaging, license plate reading and facial recognition.
This takes public surveillance a step beyond stationary cameras, and the challenges to personal privacy are clear. The K5 could do a whole lot of good by deterring crime, especially in neighborhoods that lack the resources to field an adequate police presence.
But where do you draw the line?
