These are lame charges. I can't believe that he fell that far for them. They aren't violent crimes or drug use. To me those are the red flags. Hell I got a public intoxication charge for quoting the blue collar comedy tour. So that doen't bother me. Driving on a suspended license is just youth and he will grow out of that.
I tend to agree with you that he can (hopefully has already) grow out of this stuff. It's not good but clearly there's much worse trouble he could have gotten himself into.
The slide down from 2nd round to 6th round probably cost him a Million bucks so I'm guessing he's paid a much higher price than most and learned his lesson.
