While I personally do not drink and never have, I feel Frank Mir really put it into perspective. The numbers of people who drink and drive (And are not caught) is staggering. Jon Jones has made a huge mistake, especially considering his previous comments regarding the matter. I expect Jon to learn from this and to continually grow as a fighter and a man.
As far as Jon Jones and his religion... Well, even the Dalai Lama makes mistakes. Religion is (Amongst other things of course) about the pursuit of perfection. So long as you learn from your mistakes and do not repeat them, I would say you are on the right track.
