In the United States, the Pentagon via DARPA (Defense Advanced Research Projects Agency) plans to be in a position to create police officer robots between now and 2025, capable of patrolling our streets and protecting citizens.
They would be able to take decisions by themselves, impose the law by force and use weapons.
In South Korea, a similar project is also under consideration and could emerge even sooner.
These humanoid police officer robots would act autonomously or could be operated at a distance by remote control.
Watch a pretty convincing video demonstration produced last year by CGI studios:
