These twins thought they had bulletproof alibis...

10. Probably the most famous lawbreaking twins of all time, Reginald & Ronald Kray ruled the East End of London with an iron fist in the '50s and '60s. After being dishonorably discharged from the army, they built a criminal empire centered around the nightclub they owned. The Krays led a double life as both famous celebrities of Swinging London and ruthless, murderous criminals. They ran a profitable protection racket and organized armed robberies, arson and other acts of violence for decades. Their criminal house of cards collapsed when police gathered enough evidence to tie the brothers to the murders of George Cornell and Jack "The Hat" McVitie, two low-level gangsters. Both were sentenced to life in prison.
