DSK, Meet the US Justice System

It was with some disbelief and dread that I read this story, regarding the leader of the IMF attempting to rape a hotel maid in Manhattan. But so often when ugly things come to light, we wish they would just go away (much like DSK attempted to do when he booked it to the airport shortly after the attack allegedly took place).
It wasn't disbelief rooted in the idea that DSK must be innocent, as his wife has said. I think that privileged, powerful, white men perpetrate or attempt to perpetrate, and think it's perfectly acceptable for themselves to perpetrate, crimes of this nature. My initial disbelief was that the NYPD acted so quickly and decisively.
This isn't because I doubt their ability. It's because in the US as a whole, we have these underlying assumptions that frequently prevent justice from being done at all. The assumption that the victim, in this case a working-class immigrant woman, is not trustworthy and was probably complicit. The assumption that forcing oral sex isn't rape. The assumption that there was a misunderstanding somewhere, and therefore justice is a wag of the finger before the perpetrator is allowed to get back to his life. The assumption that if we pretend this stuff doesn't happen, then it doesn't.
It's for these reasons that I'm rather shocked that the NYPD hauled DSK off his flight and down to the precinct. It gives me hope that in spite of all those assumptions that often prevent justice, that this time justice will be done in the form of a guilty conviction.
But it's only been a day or so, and already DSK's apologists have decided it's a conspiracy and he's innocent and blah blah blah. I'm just waiting for the accusations that the victim was a regretful prostitute or some such nonsense. The fact that I expect that crap to start floating around is pretty telling.
Maybe I can be hopeful. Maybe this signals a greater turn of the tide, where society doesn't just pay lip-service to the awfulness and prevalence of rape but actually attempts to do something about it.
