He got life plus 1000 years, though I suspect, with good behavior, he can shave that in half.
I once read a story of the gangster Louis "Lepke" Buchalter, who had spent a few years on the run from the NYPD and the FBI - and from some fellow mobsters - after deep involvement in some narcotics trading, loan racketing and extortion, Finally someone in the mob, toigether with Walter Winchell, managed to negotiate a mutual deal with him and D.A. John Dewey, making Buchalter believe he would be treated as a crown witness, get tried himself only for some minor crimes and get a good plea bargain and a fresh start. So he.comes out of his hole and is driven into Manhattan by a mob bigwig, finally appearing on a rainy night with sunglasses and walking up to a black limo on a corner of Fifth Avenue. Inside are Dewey, Winchell and J. Edgar Hoover. Wincehll is at the stering wheel and opens to let the newcomer in. "Mr.Hoover, this is Lepke."
"How do you do?"
"Glad to see you" Buchalter responds and slips down in the back seat next to Hoover. As soon as the car stars, Dewey begins addressing him, and poor Louis realizes that the guy who was going to give him an easy ride doesn't make any mention of the prospect of a bargain or a crown witness status - either he doesn't know or he isn't going to honour the deal - instead he's detailing crimes which he's already said in newspapers around the city would send him to jail for five hundred years. Winchell says nothing about this change of tack, just keeps driving.
"I wanted to get out of the car as soon as I heard that" Buchalter said some time later.
(Actually he would end up in the electric chair at Sing-Sing after they found four good murder charges against him)
