I'm going to tread lightly here. The evidence IIRC is that D. Washington went to Tyson's room, voluntarily disrobed, voluntarily let him go down on her, and at some point after that she claimed that she was raped. Look, I'm not some caveman. If a woman says stop you stop. Been there, done that, it sucks but I can live by that rule. I believe that any man who forces himself on a woman disgraces himself as a man.
That being said, I think there's some reasonable speculation as to where that encounter between Tyson and Washington may or may not have crossed over from bad sex to rape. I figure that if she let him go down on her she let him put his dick in her, or at least that's some reasonable expectation at that point between consenting adults. At some point she realized that Iron Mike wasn't the gentle sensitive lover she envisioned and she wanted out. No doubt Tyson wasn't paying fuck-all attention to her needs and finished up, told her to get her clothes on and get the fuck out.
Washington had no injuries. She was not struck, didn't show bruising consistent with being restrained, I think her injuries were to her pride and hell hath no fury. Mike Tyson was an easy target and public sentiment was leaning against him and good luck finding a juror who didn't have an opinion on Mike Tyson. None of this makes Tyson anything other than the tremendously flawed individual he is but I think he got the shaft on that one.
But that's like, just my opinion man.
