It only takes slow evolution of the CCTV infrastructure to reach those levels, though. Here's another step: Police propose minimum image quality standards for CCTV systems, including private and commercial ones. Again, I'm sure that the notion is that it'll be easier to identify criminals captured on camera if the quality is better. But it would also be easier if those cameras were tied directly to the police station. And then it would be easier if those images were constantly processed to find wanted people. And then it would make sense to start profiling actions.

Again, I'm not saying that any of those things are going to happen, but I think it's worth it to attempt to make sure that they don't, or at least be aware of the situation so that you can see when further steps are taken along those lines.
