Yesterday, a couple hundred Columbia students walked out to protest the war, and CTV News has video, and you'll see protesters chanting for troops to be removed as they march on and around campus (apparently there was free hot chocolate during the cold day). Interestingly, the Columbia College Democrats removed their support for the walk out "in part because of disagreements over whether to call for divestment," according to the NY Sun.
However, there was another incident that countered the walk out. From the Columbia Spectator:
As the strike began, fire alarms went off in Butler Library, Lerner Hall, Hamilton Hall, and Kent Hall, forcing an evacuation of the buildings and an investigation by the New York Fire Department. Later, a group calling itself the Union of Students Advocating for the Preservation of Tedious Paperwork claimed responsibility for the fire alarms in a statement delivered anonymously to Spectator, which called the protest "symbolic, harmless, [and] permissible" and called the strike's organizers "aspiring bureaucrats."
"We pulled fire alarms on campus to disrupt the scripting of both activism and student life," the statement said. "No one should be willing to sit idly in the face of war, nor should they be willing to act as mere extras in a farcical theatre of resistance."
The Columbia Daily Spectator also has a documentary of the strike.
