What should the commissioner do if Michael Vick is convicted of dog fighting?

I don't want to judge a person on hear say no more than I want to be judged. If Vick is found involved in these dog fights, the commissioner should be as stern as he was for Pacman. I have seen dogfights and it is not a pretty sight and anyone who could be so inhumane to even permit such acitvity should be pentalize to the fullest extent of the law. I am not a die hard animal lover but once you have seen something like that, you won't remain the same. If Vick is involved in any way, he should be held responsible and accountable for that role.
