[xawvoqyx] Accurate paintball gun

Create a device that can disable security cameras with paint balls.  Unlike a handheld gun, it automatically aims using computer vision.

Against a surveillance state, this could be a powerful weapon, usable for good or for evil.

A laser might be a better alternative, with an advantage that one cannot forensically examine the paintball splatter to determine who (visible in the footage before the shot) fired it.  Possibly combine the two ideas in succession; you probably want laser range finding anyway.
