So, to hell with shanks and smuggling drugs in your ass. The newest threat to prison security.... drum roll please....
Dungeons and Dragons
I wish I were kidding.
There, an expert on prison gangs argued not only that having a Dungeon Master issue direction to other players “mimics the organization of a gang”, but that the game encourages players to become obsessed with mentally escaping the restrictions of prison life, which could threaten “the safety and security of the institution.”
Funny, that guy just described my JOB. Only I didn't have to stab someone to get here and the anal rapings are a little less frequent.
