Wow, that is sad. She has been through so much already, and to arrest her is a huge slap in the face. There is no telling what is going through her mind, especially at a time that she is probably very vulnerable, scared, and confused.
She is the Victim, and does not deserve being treated in the way she is. I can see how they might need her testimony to get a conviction, but it seems that there would be other ways to do it, where she wouldn't have to actually be in the same room as her rapist. If they absolutely had to detain her, it should have been under her terms, and she should be treated with utmost respect, compassion and kindness especially during this very traumatic time for her.
This is setting a bad precedent, and I bet a lot more people will now think twice before even letting the police know about a crime committed against them.
My thoughts and prayers go out to this Young Lady.
Here's another story about it too.
