Ok, so, I'm trying to do a story/rp about a female cop (solo undercover, no backup) that is trying to bust a criminal and his organization. She takes a job in one of their strip joints. The cop is not going to get her evidence, but, in the process, she has sex with the customers and is incriminated herself (blackmail evidence). How does one go about "legally" entrapping a cop with prostitution? I want to make it seem at least real enough and not just make it up.
