I watched the episode last night, and didn't really care for it. I guess I'm an old-fashioned gal who liked to know who the bad guy is and some CLOSURE at the end of the show! I felt like I was reading that dumb story about the princess and the tiger again--which door did the prince choose??
As for your question, it really made me wonder about how cases like this really go down. I don't know if there was sufficient evidence to prove "beyond a reasonable doubt" that he was guilty, but then there wasn't enough to prove that he was innocent, either. I'm sure going through something like this would be horrible, and like you said, I wonder why the girl character would go through that if she made it all up.
