Calling people idiots and telling lies about their opinions is not making your case.
In many cases, accusers actually know who the perp is.
In this case, we don't even know if a crime was committed.
It's entirely possible Shannon ignored her advances and she is seeking revenge.
It's also possible a crime was committed and she misidentified the perp.
In her own words, she didn't see who fingered her. She believes it was Shannon. By implication, she doesn't actually know for sure.
In the same way that by implication, no accuser ever knows for sure.
You're trying to use evidence that doesn't support a claim to support it.
You said "in her own words". Show me those words. The police report says she stated "once she got close to him, the male started 'grabbing' on her and 'grabbing my butt' to pull her towards him". She stated "he pulled her to him and nearly immediately placed his finger under her underwear and inserted it into her vagina". She stated "because of how crowded the room was, and her position next to the male and the wall, she couldn't move or 'do anything' while this happened". She stated "this also caught her by surprise and she was in shock." She stated "the physical contact lasted only approximately 30 seconds before she was able to get away from the male and exit the room". She stated "the male used one hand to pull her towards him". She stated "the male's hand was around behind her buttocks and entered her vagina from behind". She stated "she guessed the entire encounter was approximately one minute long". She stated "the male's finger was inside her vagina approximately five to ten seconds".
The notion that "in her own words, she didn't see who fingered her" is something you drew from the motion filed by TSJ's attorneys. None of the statements she made that are public stated any such thing. The only place that language can be found from what I have seen is in a tweet from an Illini fan lawyer, and in TSJ's lawyer's motion.
Remember, these lawyers posted the DNA stuff to slut shame the accuser even though they knew the DNA found on the accuser didn't exclude their client. They leaked the stuff about her Googling KU and Illinois athletes to make it seem like she was picking a target, even though Googling athletes to figure out who it was was perfectly reasonable for someone in the situation she claimed she was in. Their literal job is to present things in a way that creates reasonable doubt, and that's what they're doing.
