They're fierce, brutal and ruthless, and bent on leaving their deadly mark on the streets of America. From the inner cities to the suburbs, from the West Coast to the East.

They rob, kill and terrorize, shaping their times and their turf. Both former and current members offer solid insight into why gangs exist, how they operate, their increasingly destructive methods and the alarming rate at which they have spread.
