The result was the 1993 Mumbai bombings.
6. John Dillinger: Escaped from prison using a wooden gun
You might remember the iconic scene from Sholay where Jai and Veeru escape from prison using a piece of wood. While that was a reel incident, 'public enemy number one' John Dillinger had managed to do just that in real life.

7. Griselda Blanco: Invented the concept of 'motorcycle assassins'.
Even though the name might not ring a bell, Griselda was once the 'Queen of cocaine'. She was the one who'd invented the concept of motorbike assassins; where gunmen rode by their victims on motorcycles, shooting bullets at them.
Ironically, she was killed by the very concept she invented when 2 motorcycle assassins shot her to death in 2012. She was 69.

One of the biggest heroin dealers in the 60s and the 70s, Lucas had specially flown over a carpenter who'd build a fake bottom under the coffins so that he could smuggle in heroin.
To make the process look authentic, he used to dress up as a Lieutenant Colonel.
Moreover, he's great friends with Richie Roberts, the cop who'd sent him to prison. Richie is even godfather to Lucas' son.

12. Meyer Lansky: Stood up to a bully at school. Went on to start a crime syndicate with the same bully.
Growing up in New York, Meyer Lansky not only stood up to a young boy and his gang who wanted him to pay 'protection money' but also made fun of them on their faces.
The boy was so impressed with Meyer's act of defiance, he started a crime syndicate with him that continued till they died.
FYI, the bully was none other than Lucky Luciano who'd go on to become a feared name in the underworld.
13. Lucky Luciano: The man who just won't die
