An Occupy demonstrator holds a sign as he sits inside a bank building during May Day protests in Oakland, California May 1, 2012. Occupy Wall Street protesters massed outside banks, meditated in public and staged anti-corporate song and dance routines on Tuesday in a May Day effort to revive a movement that triggered nationwide protests against economic injustice last year.
