with enough check and balances I think this is only a positive. It will lead to faster and more accurate police work.

It will also take the "life was in danger" aspect away from policing in which people are killed unncessarily. A drone can target a leg of a suspect without having anyones life in danger.

The police are not moral arbiters. They are policy enforcers. So you basically have a robot that has a soul and fears mortality going around right now. This is more dangerous than actually having a robot do the job.

Some police are community protectors but that has gone the way of the dodo bird a long time ago. Especially in big cities.
