The Brits have gone all in on the surveillance society with their CCTV cameras all over the place and now the Online Safety Bill. Still early days, I'm sure it'll be expanded at every opportunity. Maybe 1984 is the blueprint. In the US the fundamental Christians are grabbing power and they're taking flamethrowers to books and talking about tracking women who may go across state-lines to get an abortion. Self-censorsh…
A good example is my partner getting pickpocketed on an empty tube train, which surely should make finding the person easy, right? Nope, the Met told me they'd need to go and pay the train maintenance company to retrieve the recordings from each carriage on the train, and they're not going to do that over a wallet.
In practice it works pretty well, because it implicitly sets a very high bar on the severity of the crime that would warrant retrieving dozens of recordings and tracing people through them. Skripal poisoning or murders get that treatment and are solved pretty quickly. Small scale crime (or whatever dystopian thought crime scenarios people imagine) doesn't.
