Whoah those are some ridiculous heists! Was just Googling this because I just interviewed Spain's greatest bank robber... he's still alive! He was an absolute robbing machine during the 80s and 90s in Barcelona, although not sure what his biggest heist was. He used to do three banks in a day during his prime though. I attach link in case it's of interest: http://www.urbantravelblog.com/feature/gangster-lunch-barcelona/

How are these successful robberies when most of them got caught?
