Too late? Really? I think not.
Maybe you've read about those red-light cameras that were all the rage a while back. I've never seen one, and it wouldn't matter if I did - I don't run red lights, so it's not an issue. If you really followed those stories, you also read about the large number of communities where the citizens got pissed off and decided to have them removed. So the towns did. Not everywhere, certainly, but in enough places to convince me that after they were put up, it wasn't "too late".
The cameras will stay so long as they don't cause issues. When they do, they'll be removed - perhaps by popular vote, perhaps by "citizen justice". But they'll go if they're causing problems for people who are just going about their lives. Don't misunderstand - if enough people think, "I don't like being watched", that's causing problems. If no one cares, they'll stay.
If they aren't causing problems, what's the issue?
