If you're an orc or a wizard, you'd better keep your nose clean.

A three-judge panel of the United States Court of Appeals for the Seventh Circuit weighed in Wednesday on a matter of grievous import to the nation's prisons: Dungeons & Dragons. And the Court's ruling was bad news for naughty nerds nationwide, concluding that the innocent-seeming board game was inviting trouble.

The case brought before the Appeals Court argued that D&D inhibited prison security, because "cooperative games can mimic the organization of gangs and lead to the actual development thereof." And therefore Kevin T. Singer, a long-time dungeon-explorer sentenced to life in prison in 2002 for bludgeoning and stabbing his sister’s boyfriend, was denied access to his magical staffs and pieces of gold.

According to the published ruling, Captain Bruce Muraski, who serves as disruptive group coordinator for the Waupun Correctional Institute in Wisconsin, elaborated that "during D&D games, one player is denoted the 'Dungeon Master.' The Dungeon Master is tasked with giving directions to other players, which Muraski testified mimics the organization of a gang."

In other words, the case didn't hang on whether the dice were loaded or the game's books were cooked or seditious. It argued that limiting the use of board games would deter gang activity. The argument had more nuances than a 12-sided die; for all the legal details, check the Geeks Are Sexy blog.
