From ABC Denver via Cryptogon:
DENVER -- Undercover police officers posing as protesters staged a fight with a police commander during the Democratic convention, and it was so convincing they were pepper-sprayed by a deputy who wasn't in on the ruse, a civil liberties group says.
Yeah, people who are anti-violence and anti-war are SCARY and it's a great use of police resources to infiltrate them, because god only knows what people who tend toward pacificism might do!
The officers pretended to struggle with the Denver police commander so it would look like they were being forcibly removed from a big demonstration and their cover wouldn't be blown, the American Civil Liberties Union of Colorado said.
The ACLU said it obtained a police report on the incident under a state criminal justice records law.
In a letter to city officials, the ACLU questioned whether the fake confrontation worsened a tense situation with demonstrators and violated police rules.
Damn those American-hating commies at the ACLU! They mess up all the good fun!
UPDATE:
Thanks to corvo, I have to add this amazing link, the T-shirt that the Denver cops were promoting before the convention that jokes about "beating the crowds":
