I suggested this idea on the police sub and they absolutely hated it. For suspects that are possibly giving up, have a mechanical hand cuff and have them cuff themselves before the officers come out of cover (cameras, latch that detects it's closed correctly, maybe attached to a heavy ass robot.)

For non-compliant suspects, pepper spray or taser deployed from the robot.

They said the suspects would use the robot as a weapon and many suspects would try to break it just out of spite.

But if it means both the officer and the suspect survive I feel like it's worth it.
