I was also groped when drunk around that time - I got falling down drunk - carried to the infirmary - and while on the table, the orderly did - stuff. I never bothered to report it, because at that point I knew I was leaving that school at the end of the semester, and I didn't see any point. I would not be able to identify him in a lineup - I couldn't tell you anything about him. And it happened to ME, about as long ago. (1980, actually). I did remember the cute girl in the infirmary the next morning. But not much else.
But, did you go to a therapist in 2010 and say you were so broken up by it that it impacted your whole life? I'm going to guess "no" on that one. Likely because, well, it did not.
It is at least as likely that this never happened to Mrs. Ford, and if it did it is equally likely it wasn't Kavanaugh. If it was really that big a deal, so much so that she needed therapy for it 3 decades later, she would have done something about it at the time.
I am prone to believing accusers if they accuse in a reasonable period of time and there's no reason to reasonably assume there is an intent that is nefarious. She loses on both of those caveats, and all of the caveats of being the eyewitness.
I am far more likely to believe she is lying than telling the truth, and I think most honest people feel the same way. That, of course, leaves out people like Trans and Sap and Salmon.
