The reasons for the shooting of Jack Giordano have never been fully explained. However, its thought that he withheld money owed for loan sharking or either pressed a usury associate too hard to pay money extorted from businessmen. Whatever the reason Giordano was grievously wounded. He ended up completely paralyzed from the neck down. My e-book looks at the Gambino extortion ring which flourished in the 1980s on Manhattan's Upper East Side.
