Am I mistaken or did the school administration or a student government organization kick him out? If so. How can he come back?
The school ultimately makes the decision on whether to kick him out or not, and they made the decision to let him back in.
I hope this is simply a matter of hanging with the wrong crowd. This is the first time that anything like this has happened under Saban (where somebody is dismissed then comes back) that I know of, so I would assume there are some sort of circumstances that we are unaware of. I know Pettway's HS coach, and he doesn't allow shenanigans on his team. His coach is a good guy from a good family, and never would have tolerated somebody being a thug. He runs a very clean and solid program. I guess that's where it's hard for me to grasp that this kid is some sort of hardened thug that is unreachable. But, people change sometimes I suppose.
