You know what I think? I think you are way too involved in this situation. No matter how close a friend you are, you can't make her believe what she doesn't want to believe. I think it doesn't matter a damn whether the brother called the cops or the hospital did or if she did or if the PO did. They got called, whoever did it, and they found sufficient evidence to make an arrest. Whether the DA will decide to prosecute or not, we don't know, but it won't be her choice either way. The DA most certainly can proceed without her okay, whether she wants to think so or not, and she damn well better not lie in court or she'll find herself in real trouble. That's what I think.
