Cops are allowed to conduct sting operations against the citizenry. Surely they can have no objection whatsoever to having the favor returned? After all, if the police are obeying the law, they have nothing to fear, right?
Bingo. How many times have I read on this thread that "if you aren't doing anything bad, then you have nothing to hide" BS. Well if the cops aren't doing anything illegal then they won't mind having a video camera trained on them every second that they are on duty. People have to remember they work for us dammit.
The fact that I find it disgusting when the cops do it to the citizens does not mitigate against it being disgusting when the tables are turned.
Foul is foul.
God save us from the day when the best standard of practice for American citizenship is defined as "whatever corrupt agents of the state can get away with doing."
