“Political activists planning protest rallies at the upcoming Democratic Convention in Denver have their stomachs in knots over a rumor about a crowd control weapon – known as the “crap cannon” – that might be unleashed against them.

Also called “Brown Note,” it is believed to be an infrasound frequency that debilitates a person by making them defecate involuntarily.”

The funny part is the activist who claims the Brown Note was used on him at a protest in 2004. He messes himself after facing SWAT teams firing rubber bullets. Naturally he assumes they must have been using a supersonic ray gun.
