Voluntarily.Since the appeal is officially in progress, he doesn't have to report and in the wildest of all scenarios, the case might get passed up the line to someone who overturns the verdict and frees him from all requirements. But he's going in anyway, and he also issued (through his attorney) a quasi-apology. 'Quasi' may be generous. He can't admit to hate and he doesn't think he meant to embarrass or humiliate Tyler. Possibly because he still doesn't see it, maybe because someone is worried about the civil end of all this and saying too much here could get him later, could be a combo. But he did at least say some kind of sorry.
Going to prison now, though...
Maybe it's about public image. Perhaps he realized he might never do any better in the sentencing department and this way, he could say he served should a harsher one come along. But is it possible that he finally realized that what he did was truly wrong and he's beginning his own self-imposed penance at last?
I'd like to believe that.
I wish I could.
