Well, in your opinion, only you don't know enough to crucify her and that is fine.
Many of us, in our opinions, know enough to crucify her, and that is our right to do so. I'll tell you what- if my daughter was killed in such a manner and another woman knew it was going to happen (come on, think we're witless lemmings here?) and did nothing about it, then took her phone with her to destroy it, you think I would need more evidence to crucify this woman? I don't know how poor Kelsey's family is staying so classy and silent- I would be fuming and have a hatred and rage towards both PF and KK. I don't discriminate. Only difference between the two- one was planning the act, while the other ignored the planning. So yeah, I am crucifying her- I think of her little baby who will never feel her loving mother's arms around her again, her parents who lost a daughter, her brother than lost his sister. I could never look them in the eye and tell them not to crucify her, she did nothing wrong- for God's sake, she had her phone and was willing to destroy it, instead of turning that monster in!
You can defend her all you want, fine by me. I can skip over or ignore people's comments I don't agree with and be respectful about it. But I will not change my mind on this woman- she is just as sick and evil as the jerk that killed Kelsey- both are monsters.
