Las Vegas is also known as “Sin City,” and the place where if things happen, “they stay in Vegas.” It's a carnal playground where you can indulge your deepest, darkest fantasies and maybe even make your fortune. The Mafia was a fixture in Vegas during its glitzy glory days and transformed it from a wild and woolly honky-tonk town to the entertainment capital of the world. Along the wild way, the Mafia fell from its lofty perch and was reduced to scrapping out meager bucks from low-level rackets while corporate suits raked in the big bucks.
