FILE - This Monday, Dec. 12, 2011 file photo shows Iraq war veteran Scott Olsen, who suffered a head injury during a protest in Oakland on Oct. 25, 2011, signing a petition before speaking at a rally at Frank Ogawa Plaza, in Oakland, Calif. Olsen, the Marine Corps veteran whose skull was fractured during an Occupy Oakland protest, was struck by a police beanbag round, not a tear gas canister as initially thought, his lawyer said.
