This might have a side-benefit of not amping up the officer with extreme shouting. A loud megaphone, tactical breathing and a calming voice can defuse more situations instead of self-fulfilling prophecies causing bad outcomes.

Meta: also, the US needs more of citizen-led policing a-la Michael A. Wood, Jr. where the police are part of, and communicate with, the community, instead of being merely a mandatory, occupying, paramilitary mafia resting on the monopoly on violence with impunity, lackadaisical/inconsistent training and blue wall of silence.

This is a cool idea for IoT based policing. As a public entity, they should be confident for all actions to be scrutinised and hold up in a court of law.

I was going to suggest connected guns (for additional data harvesting) but realised a connected gun that could be hacked is a terrible idea.

As long as the firing mechanism is purely mechanical hacking the gun becomes meaningless. Picture gun with attacked tiny video camera, hack it and the guy is still holding a working gun.
