The noted “horror core” hip hop duo, Insane Clown Posse, has filed suit against the Federal Bureau of Investigation. The FBI apparently labeled ICP fans, known as “Juggalos,” as a “loosely-organized hybrid gang,” to which ICP has taken offense. ICP tried to get the FBI to explain itself, and filed a FOIA request for information that would justify the designation, but the FBI was not forthcoming. So now ICP is suing. Bang! Pow! Boom!
