That article, right there, talks about the two issues (one in Georgia and the big one in Las Vegas) that got him suspended in April of 2007.
Then if you read the Clayton piece that runs right down the side of it he mentions the fact that there were conditions to his being allowed back in that he has broken on at least occassions, including being out after midnight and driving around without his license.
At the end of December, or early January, this year he got in trouble with a woman accusing him of having attacked her in a club. She later withdrew the complaint, but again, the fact that he put himself in such a position, when he knows what he's suppose to be doing to get back in the league, shows he's not real smart.

That story documents where, barely a month after getting his 1 year suspension, where he went out to a nightclub the night before he was to meet with the commish about getting his suspension reduced, or changed. Again...not the smartest guy.

Another article talking about the stuff surrounding his situation in regards to the nightclub shooting that was one of the things that got him in trouble originionally.
And those are just a few links I found on the things that have gotten him in trouble, and continue to keep him in trouble, by simply typing in his name and looking for just a few moments.
The guy is an idiot, he's trouble, and he deserves nothing better than what he's getting right now.
