I'm not saying this sexting with a minor thing is going to turn out to be BS like Rolling Stones' infamous "A Rape on Campus" or whatever, but some of the facts seem pretty weird. Regardless, the FBI getting involved is a good thing. He'll either get quasi-exonerated or catch charges and get nailed to the wall. On the crime and punishment side, justice will be done.
As far as using power/celebrity/false promises to sleep with much younger women who had aspiring talents, I think everyone agrees that the behavior is gross/shameful but not criminal. He seems ready to get his comeuppance for that shit, which the Times article most certainly delivered.
His BEST case scenario is: (1) the minor sext shit is misrepresented or false, (2) he spends 2-3 years of public exile w/ no album releases, no tours, minimal tweeting, etc., (3) quietly returns to music in a less visible role, and (4) is able to make a humble "comeback" by giving a totally honest high profile interview.
I think people can forgive him for most of this shit, but he's going to fucking need Oprah to endorse him as "rehabilitated." Only The Oprah has that kind of power.
