I think there's a ton of valid reasons to not like the cameras. I just question how much of an impact it will have.

It comes down to what happens first: a scandal that breaches public trust where the police misuse the cameras or a situation where the cameras can easily be pointed to as a part of the solution, i.e. "in the stolen car with kid(s) inside"

Beyond that? I'm not sure it really changes the public/police relationship much. Even with media coverage, most people aren't going to notice this shit since, unlike the speed/red light cameras, they aren't getting a ticket in the mail.
