The case centers around surveillance video, which shows the deputies repeatedly hitting Petrov in San Francisco's Mission District, following a car chase.
The defense wants to know why the district attorney hasn't filed charges against Petrov.

"If two police officers are assaulted with a deadly weapon and they have this chase, and you have this guy, who is a career criminal, why not file? It's your county, it's your citizens," asked Bill Rapoport, one of the Defense attorneys.
The defense says the surveillance video is a key piece of evidence and will help them prove their clients' innocence.
