I also don't have a problem with what Brent said. If someone messes up - in this case, messes up badly, you have to lay out the penalty, he has to serve it and it would be in the best interest of all parties to show a path to redemption. Without that path, the only alternative is more crime. That is exactly what Osborne attempted to do with LP back in the day. Unfortunately, for TO and LP, it backfired on them both, somewhat marring the program.
In the case of Mixon, he did the crime, he did the time (that was given to him). For the internet police to think it is their job to continue to punish him for the rest of time, they would be better served doing something more productive.
