I believe four years is the maximum for any one of the charges. It seems unlikely he'll get that. And, any jail time would probably run concurrent rather than consecutively. So, four years would be the most he'd receive in sentencing.

However, apparently, if he's given less than a year's prison term in NY, he must serve it at Rikers Island. He wouldn't be moved to the Club Med kind of prison, for example. If that's the case, I'm rather hoping he'll get six or eight months and serve them all at Rikers.
