Remember, as a civilian, you are not allowed to carry a gun in San Francisco. The whole whole of San Francisco County has 2 people with active CCW permits residing in it. You can’t be trusted to be responsible with your firearm. You might accidentally discharge your gun into a buddy or something like that. A real professional wouldn’t just leave his gun on the roof of his car and drive off, losing it. Only law enforcement is professional enough to be trusted with guns in public.
