According to The Village Voice, Juggalos -- "traditionally fans of the musical group the Insane Clown Posse" -- are a threat to America.
That same definition could be applied to, I dunno, college undergrads, hipsters, off-duty garbage men. But here it's strapped on Juggalos, along with the Latin Kings. ("Social networking websites are a popular conveyance for Juggalo sub-culture to communicate and expand," the document also helpfully noted.)
Initially, this seemed amusingly ludicrous, another example of a federal agency looking foolish for its cultural ineptitude. "The FBI has recently had difficulty distinguishing ordinary American Muslims from terrorists," wrote Wired's Spencer Ackerman, who first wrote about the FBI's Juggalo gang-list inclusion. "Now it appears it has a similar problem distinguishing teenage fads from criminal conspiracies." Except that a seemingly silly judgment tucked away in a federal document is beginning to have tangible consequences.
