When news articles mention the maximum, especially in headlines, it feels a bit misleading. It seems there's a decent chance there is little or no prison.
Every time I hear stories about someone being wrongfully committed while having nothing to do with the facts I'm super scared.
A person I know who lives in Sicily shared the very same exact name with a local criminal who was often mentioned in tapes and got arrested and jailed for few weeks till it was cleared it was somebody else. It even was a strike of luck the other one was arrested few weeks after him, and you know how it goes in small Sicily villages, everyone knows each other so he also occasionally would find himself in the same places known criminals would hang out, same super markets of bars or restaurants.
Another person I know spent a similar amount of time accused of aggression towards police. He was stopped for drunk driving (which isn't a jailable felony in Italy obviously) and when he was asked to leave the car he leaned on cop's car and they "framed" that as an aggression while the guy simply couldn't keep his balance so he half felt on the cops vehicle. He was cleared thanks to cameras.
