The punk will walk away with a slap on the wrist and sent on his happy way
Since this is going on in my town.....
While this is a very conservative area...I would not call the people of E TN "star-struck" as one of the Dummie posters did.

This is also an area, where people hold their privacy and right to privacy, dear.
I don't think the kid will get 50 years or anywhere near that, however, he did break the law, regardless of who's email account it was he hacked.....and there seems to be no question that he did hack it.
I don't know if he will end up with just getting probation or not. He is not a "bad" kid....just one who did something incredibly stupid and yes, criminal. I do think punishment is warranted, but putting him into a general prison population will probably do more harm than good.
I think he can stay in the county jail up to 11 months and 29 days....a longer sentence requires going to prison. I would think he will end up in the county jail for some period of time. For a kid who grew up as he did, that should be enough to scare the crap out of him and keep him from doing anything incredibly stupid again, and serve the rest of his sentence on probation.
