Amid the spate of random clown sightings around the country that made up the 2016 “Clownpocalyse,” Allan Lasser began filing for police incident reports regarding clowns. For Halloween, we’ve compiled a list of the most disturbing details to come out of those requests.

Earlier this month, Insane Clown Posse fans marched on Washington D.C. to protest the FBI’s 2011 designation of Juggalos as a “loosely-organized hybrid gang.” However, Bureau files show that ICP first came on the FBI’s radar three years earlier, when the Bureau threat assessment of the annual Gathering of the Juggalos included allegations that the Family was engaged in a full-on turf war with MS-13.

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.
