No, he would not get off in California or any place else. Bank robbery is a federal offense not a state or local one.
Most of the time, bank robbery is covered under state prosecutions. If you do multiple robberies and shoot the place up…that will get the Fed’s involved.
I think people would be surprised as how many bank robberies go unsolved. I was surprised to learn that when I worked at a bank.
Hint: If you are planning on robbing a bank, give video surveillance and cop response times some consideration. You can work around that stuff and be on your way pretty quickly.
