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.
It's funny, in Illinois they altered the judge's plea script a couple of years back. They used to say "has anyone made you any promises in regards to this plea?", but now they say "except for the prosecutor, has anyone made any promises.."
It is hard, because if you are innocent you have to make a tough choice. Two weeks after my arrest I was offered a plea to be released the next day. I refused and it took nine and a half years in pretrial custody to actually get my case heard.
