According to statistics there's roughly 5,000 banks robbed every year and most of those bank robberies are solved and the bank robbers are usually captured within a few days to the same day.
That equates to roughly 130 to 140 bank robberies per day throughout the USA and also some other countries.
Getting away with bank robbery now is very hard with all the technology such as cameras etc where's way back in the old days there were no cameras to capture the bank robbery suspect.
But you're very unlikely to get away with a bank robbery today and if you do you'll only get away with maybe $3,000.00 to $5,000.00 at most.
And when caught you face up to 25 years to life in prison over the bank robbery and if you use a weapon in the commission of a robbery you get more time added.
