Here is the only thing I have seen. This isn’t the evidence the DA/police have but the sworn affidavit. Make of it what you will.
I mean I've seen a lot of alleged victim affidavits. Points in her favor:
1. She reported it within 24 hours. That's pretty rare and usually a pretty strong point in favor of credibility. Including subjecting herself to an exam.
2. She went through a lot of faces before she settled on Shannon. That means she wasn't looking for the first Black dude she could find. Also cuts against the idea that she struggled with cross-racial facial identification if she was of another race, which is a legit issue.
3. There appear to be witnesses at least to the before and after part that can either corroborate or dispute her version of events, including a contemporaneous allegation. But at the very least, her phone puts her where she says she was, and her friend corroborates at least the before and after parts.
4. She doesn't claim she was drunk or drugged, and she doesn't claim the encounter lasted for very long at all.
5. As of yet, no reason to believe she had any idea who he was, that he was "famous" or that she would otherwise gain from a false report. (Of course, new info could change that).
Is it enough for conviction on its own? I mean sure, but that would depend on a jury deciding she was credible in her story. People think you can't be convicted just on a claim. Well sure you can, if the jury believes the person making the claim. But obviously there may be other things out there we don't know that will add or subtract from her claim.
But bottom line, I have no problem with an arrest based on what I saw there. There's absolutely probable cause.
