Who Robs Banks Anymore

I was listening to the news today and was really shocked when I heard there are actually a lot of bank robberys. I just can't imagine robbing a bank these days. I mean, I don't think any of them have big piles of money in their vaults do they? There's no huge mountains of gold bars anymore right? I think all the money is transfered electronically any more. At best a bank would have maybe $20,000 on hand to cash checks on Fridays. If you think about it, that's really not that much money. Definately not worth jail time. Amazing.
