This really isn't a new concept, but I am hearing that there are agents in Hip-Hop like there were in the era of the Black revolutionaries. Basically, these people presume to be either rappers or crew members when they are really agents of law enforcement. They sit in there, deep cover, and report back. Its not foreign. Its a lot like 21 Jump Street or something.
