On a perfect autumn night in 1984, a retired policeman charged into his neighbor's garage, hell-bent on collecting a long-overdue narcotics debt.

Instead, he met two shotgun blasts-one shredded his chest, and the other ripped a hole in his back as he tried to flee. A half hour later, he flatlined in the ambulance. But this cop wasn't about to leave so easily.

The ensuing court trial released a flood of stunning revelations about three of the most extraordinary crimes in American history-

Examscam, the statewide black-market sale of stolen police entrance and promotional exams that destroyed Massachusetts' Metropolitan Police force.

A massive cocaine and marijuana distribution operation that moved a half billion dollars of drugs in less than two years.

And the daring robbery of the Depositors Trust Bank-at $30 million, one of the largest-ever heists in the world.

All involving one man-the shotgun victim, Joey Bangs.
