When uppity protesters occupy a building, they're basically signing up to get pepper sprayed and thrown to the ground. The NYT reports:

Scores of police officers wearing helmets and carrying riot gear stormed a New School building at 65 Fifth Avenue around 11 a.m. Friday, arresting 19 protesters who had occupied the building as part a determined protest aimed at the university’s president, Bob Kerrey. [...]

Witnesses said that the protesters had sought to leave the building by a side door, but were pushed back and pepper sprayed. The witnesses said that several students pushed open a door that exited onto 14th Street, and that police officers stationed outside that door applied pepper spray onto the students in the corridor and slammed the door shut. [...]

A videotape shot by a freelancer, Brandon Jordan, showed about half a dozen police officers standing near the door on 14th Street when it was pushed open from inside. The footage then shows officers shaking cans of pepper spray as they hold the door back, spraying inside the corridor, and then slamming the door shut.

Okay, that's just too much. Blockading a door in an evacuation could kill people. That's exactly what happened in Mexico City during a raid last June. And excessive force in London likely led to a man's death at the recent G20 protests. Democracy is built on people willing to take the risk of arrest and jail for a cause the believe in. Let the protesters—even those with a strange cause—leave the building, then spray 'em, toss 'em to the ground, and arrest 'em. It's only fair.
