There's the tiny issue that storage became so cheap over the last 20 years that recordings can now be kept indefinitely. In the past you had a CCTV camera, and you could store maybe a month's worth of movie (on tapes, in a safe), until you had to overwrite it. Now you just keep filming and have a never forgotten record of who lives in the neighbourhood. And if Facebook runs it though its face recognition system they get names, friends and other preferences. That completely changes the nature of CCTV recordings. The law just hasn't caught up with it, also because of prolific lobbying by the usual bigdata actors.
