Before going to Italy to shoot Season 4, Ronnie applied for a pretrial intervention program, which is basically the judicial equivalent of taking a class pass/fail. Ronnie wouldn't have to plead either guilty or not guilty to the charges against him, and those charges would subsequently be dropped without a trial if he stayed out of trouble for a predetermined period of time.
Today, Superior Court Judge Stephanie M. Wauters admitted Ronnie to the intervention program. If he keeps his nose clean for 18 months and does some court-mandated community service, all charges will be dropped. And we can forget all about it — except for that guy who will go down in history for getting KO-ed on MTV's biggest, best reality show.
