But which US governments? There are thousands of them, and they all have different policies.

We (the people) have pushed body cams on almost all law enforcement at this point, which had a noble enough motivation behind it -- but we also have pushed for and have various public disclosure laws (also well intended!) that mean those body cams are torrents of data entering the public sphere if anyone simply asks for it.

Now in the era of AI, this means anyone in the vicinity of an officer has a voice sample in the public domain, plus potentially their image.

Complex issue. I like body cams, I like freedom of information laws, but don't love this particular outcome.
