A convicted murderer serving life in prison in Wisconsin has lost his legal battle to play Dungeons and Dragons behind bars. Kevin T. Singer filed a lawsuit against officials at Wisconsin's Waupun prison after a policy was initiated in 2004 to eradicate all Dungeons and Dragons game materials among concerns that playing it promotes gang-related activity. The 33-year-old Singer is a devoted player of the fantasy role-playing game that involves recruiting others to play as a group. He argued that his First Amendment rights were being violated and demanded that Dungeons and Dragons material confiscated from his cell be returned. But the 7th US Circuit Court of Appeals ruled Monday that the prison's policy was reasonable.
