Do the MAJORITY of people think that Amanda Knox is guilty of murder? how possible for her ?

I admit she seems like she is hiding something, but I just cannot see her actually slitting Meredith's throat, and how it would be possible for her to do that? (Meredith was trained in karate and around her size ?)
Update: but I saw on several forums that the MAJORITY if not 96 % think she is GUILTY of MURDER , but why?
