I agree and disagree with you. Maybe I missed it, please correct me if i am wrong though. I don't remember reading something saying that she said it was usually tame, it sounds like your assuming that she thought that. I don't think that the chimps owner was a friend of the woman since the woman sued/or at least tried to sue, the chimps owner for 50 million, what friend does that? She did make a huge mistake by helping the owner try and capture the chimp though. I feel for her and her family about that. I don't think its appropriate for her family to sue anyone for the woman's mistake though.
Totally agree with the second part
EDIT: regarding the first part, I am going off what the story said. We all know what the media does to make an interesting story though.
