Back in 2010, Deputy Chris Pratt of Denver Police’s Gang/Intelligence Unit got fed up with his department’s lack of operational knowledge regarding the threat posed by the vicious street gang known as “Juggalos.” Pratt put together a guide on the “fanatical followers” of Insane Clown Posse. And now, thanks to public records, you too can know what it means to be “down with the clown.”

The hip-hop duo Insane Clown Posse sued the FBI this week after the agency failed to fulfill a 2011 FOIA request for documents justifying the Bureau’s designation of the Detroit-based musical group’s fans as a gang.
