Update:
San Francisco Sheriff's officers on center front police line, during shooting of Marine Scott Olsen have been verified, by way of an official list of officers.
They are San Francisco Sheriff Emergency Services Unit (ESU) officers Scott Bergstresser, Ceciel Yambao and Hugo Aparicio.

OAKLAND, Calif. -- US Marines are gathering evidence to prosecute the officers who shot fellow Marine Scott Olsen, member of Veterans for Peace, at Occupy Oakland on Tuesday night. Scott was standing in front of police to protect the people behind him, when police fired directly at him.
Scott suffered a skull fracture when a police projectile struck him in the head. After Scott was down, and people rushed to help him yelling for medics. Police threw a flash grenade at Scott after he was unconscious and bleeding from the mouth and head.

A video reveals that the San Francisco Sheriff's Emergency Services Unit (ESU) were on the front police line at Occupy Oakland when the tear gas canisters were fired. The video below shows San Francisco Sheriff ESU team member Scott Bergstresser, (whose uniform has two stripes) next to officer Ceciel Yambao.

"Multiple copies of the videos used to ID Yambao, Bergstresser and officer Hugo Aparicio are on servers. Too late for YouTube takedowns," according to a Twitter message today.

"Two questions that Bergstresser should be asked under oath: Did you fire directly at Scott? Did you throw a grenade?" At minimum, Bergstresser is a witness.
The video reveals one of the officers striking his baton at a disabled woman before the gas attack began. An Oakland officer in the background can be heard giving commands on a loud speaker.
