I've been ignoring this silliness for some days now, but since it continues to get traction in the press, I'm finally going to give in.

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.

Mark Cohen, co-founder of Re-create 68, an alliance of local activists working for the protection of first amendment rights, said he believes this could be deployed at the convention in August to subdue crowds.

“We know this weapon and weapons like it have been used at other large protests before,” he said.

Cohen, who described Brown Note as a “sonic weapon used to disrupt people’s equilibrium,” cited eyewitness accounts of its use during free-trade agreement protests in Miami in 2003.

“I think these weapons were mostly intended for military use and so their use for dealing with innocent protesters seems highly inappropriate,” he said. “The idea that they might be field testing them on people who are doing nothing more than exercising their first amendment rights is disturbing.”

Of course, scientific researchers say that the "brown note" doesn't actually exist -- and since there is no actual evidence other than loony ramblings of these aging hippies and '60's wannabes, I'm inclined to believe the researchers.

Maybe the real problem that the Recreate 68 folks have is that radicals like them are have simply become so full of crap that it is waiting to burst out in all its glory.
