>The predicted loss of a bank robbery is high four figures.

Having worked as a bank teller, that figure is much, much lower. Often they'll only get away with a couple of hundred dollars.

Otherwise you're right. I think a lot of people still have the romantic picture of Bonnie & Clyde or Hollywood style movies like Heat. The reality is that bank robbers nowadays are idiots. They're high on crack or otherwise don't know what they're doing. They are dumb. All bank robberies are investigated by the FBI, and these guys get caught.

This isn't just fear for the customers or perception, it's a dangerous situation where the loss is really not that great. Meanwhile a teller that tries to act like a hero could get himself or others shot, over a couple of hundred dollars.
