Well, up until the 'he leaned in and kissed me, I told him not interested' part, I don't think it's terribly controversial to suggest no crime had happened. Had it just ended with that, no big deal. It's just the "jamming his hand into my underwear" part that seems to approach/cross the line. A plausible interpretation of that is "touched my butt", which while unlikely to win the girl over, I don't see as something deserving of being "locked up", or, perhaps worse, having his career ruined as it surely now has.
I should add, in all honesty, I don't completely believe the girl's account of this. There's 6 or 7 things in there which just don't make a whole lot of sense to me (the "logistics" of the whole thing, to borrow someone else's word). You add in her reaction, writing a blog post detailing it, naming names, etc., the very next day it, just seems suspect (not to mention her claims this has happened before - she must be very unlucky!) . I could be completely wrong here, and defending a bad guy. But that's not a big deal, as we can see there's no shortage of white knights rushing to the poor girl's defense.
