Actually, responding again, because I want to address a different point. Seahorse claimed MB abused horses and there was a text the prosecution entered into evidence that accused MB of abusing horses. I seriously doubt that the prosecution would have failed to subpoena a verifiable witness to MB’s harassment and bullying tactics and horse abuse (all points he was trying to make) because a witness didn’t want to testify.
So, if she was asked to testify, I assume that the defense did the asking.
ETA: she was also very vocal about being fearful of MB trying to kill her. That is something I would think the prosecution would desperately want to be on the record.
