I'm not sure it warranted 30 days in jail, but it was definitely stupid. I don't think he meant any disrespect or anything, he's just a clown, and probably does stuff like that all the time and didn't realize.
He's just.... not very smart of a person. I hate it that he's had all these troubles, he used to be one of my favorite players just because of how he mingled with fans, bought dinners even in away cities, and talked with fans on twitter. I even played Call of Duty with him once or twice, as did a lot of other people. Not to mention he was talented.
It's like he seriously may have some mental issues going on, not sure.
