Most bank robberies today are solved within one to three days of the robbery and the bank robber is usually caught within 1 to 3 days of the bank robbery.
About 5 percent to 10 percent of bank robberies are unsolved but with the technology of today and the police force we have today you're very unlikely to get away with robbing a bank or anyplace.
After robbing a bank the bank robber will likely be caught within the same day and arrested and taken to jail and then they have no use for that measly $4,000.00 or less that they obtained from the robbery.
Then they'll be spending the next 15 to 25 years or more in a prison over that little bit of money.
If anyone is thinking about robbing a bank or anywhere today remember that you won't get much money but you'll get a lot of time in prison when convicted and you'll almost certainly be caught and arrested within the same day.
