The GPS device paired with a loitering drone or helicopter carrying a sensor pod, streaming a video stream that can play bird's eye video backwards and forwards, should be sufficient to track a suspect. DARPA was doing this with ARGUS in 2013 with a few hundred cellphone camera sensors bolted together; I would assume the state of the art has advanced in a decade. The saying used to be, "you can't outrun Motorola." The new hotness is likely "you can't outrun the surveillance tech stack."

Perhaps a high speed drone could do this. The trick would be to deploy something like this safely. That said, I'm not looking forward to the day where drones and AI are part of the standard kit used by police forces. The ability to cheaply surveil people clandestinely as they go about their business does not sound like a future to look forward to.

Even then you have the right to face your accuser in the US. IANAL but I think that you can't call an AI in for cross, nor a robot. Probably depends heavily on jurisdiction though.

Not to worry, skynet is already working on something better..
