It's not clear to me how the police will track down who operated what drone, especially if the drone operator is several kilometers away, perhaps not even near the launch site, and even if caught, only has a controller and headset.
This is much more like the DC sniper than a typical gunman.
Also we're already looking at a) onboard autonomy, so control is not needed or b) rebroadcast hardware that runs over LTE or WiFi. Satellite comms on the way, at least for the civilian market.
