What you describe is the privatisation of CCTV. Yes it is owned by the likes of shopkeepers, but all of it is accessible by the state on demand. So I'm afraid its not bullshit at all. Its just not owned by the government. That should be nice and safe, right? When you get don to it, its rather clever.
That makes a huge difference though. You have to go out and talk to people and ask for tapes. That ownership structure makes many automations very hard which is a good thing. Routinely scanning for suspicious activity? Nope. Automatically follow a single person from one camera to the next? Nope.

Yes, if they walk into the shop with a warrant and ask to see their tapes. They can't track us all walking around in realtime, which is a huge distinction.
