I've noticed that whenever the subject of cameras in public places comes up on traditional media platforms, there's always talk about the 'debate as to whether we want these things/should allow them'. I suspect this is a planted misdirection (†) - the government and corporations that profit from this information would love you to waste your time talking about whether we should have this kind of surveillance, because it's already here. It would be far better if we could have a debate about who should be able to access this data. For example, there's a difference between a sworn police officer accessing public camera footage, and the same footage being send to a 3rd party by the police, being analysed in a foreign country by foreign workers.
† I'm not alleging a giant conspiracy theory about direct corporate control of the media, but it is well known that businesses 'seed' articles by sending unsolicited 'fact sheets' and talking points to reporters.
