Video is useful in keeping people safe. Including from the cops. It’s about remaking the system to require court permission every time they access it, process and transparency.
Somehow we went from:
1. People can see and hear your in public
2. Therefore public places are not private
3. Therefore people can record you
4. Therefore it's okay to build a network of cameras that can track and query every place you have ever been
The problem has always been on step 2. The assumption that "public places are not private" anymore just because everyone can record you and post it on TikTok. In reality before smartphones public places were extremely private compared to being broadcast to the entire planet.
A. there is nothing a good person needs to hide (including cops, at least good ones), therefore it should be openly public to everyone and all usage logged and public (to catch abuse), or
B. privacy is important so it should be protected, and while data is collectible, nonetheless cannot be shared without consent or a court order. And none of this fake content that companies claim you gave by walking outside, setting up your phone/account/etc after buying it and being forced to sign so you didn't just buy an expensive brick, etc.
Police wearing body cameras has nothing to do with universal mass surveillance devices.
