This reminds me of something I've wondered about. Just what can a cop do or not do when they are in a sting operation. Somewhere I got the idea that they're required to tell you if you ask them if they are LE. But my gut tells me not to depend on it. I've had girls ask to see my dick as a way to assure themselves that I'm not LE, but doubt that that is reliable either. Anybody out there can clue me in?
