Police hold back students protesting the Iraq war, in Berkeley, California February 12, 2008. The Berkeley City Council is expected to vote whether to revoke a letter it approved two weeks ago telling the Marine Corps they were "unwelcome intruders" and should leave a post used as a recruitment center, one block from the University of California Berkeley campus.
