Of course, one can come to JREF and take a dim view of the thinking process of regular posters here to his or her heart's content. The problem is that, unlike any PGP site of which I am aware, there are some very serious and credentialed people here, who have no special commitment in the Knox case except to the truth. For years now, such individuals have been coming here reality-testing evidence and theories, and, in doing so, have managed to come up with takes that stand up both to science and common sense.
So, to an objective reader, this has become a kind of barrier of entry to participation, here. Come in a skeptic, but come well armed, or risk one's theories being made pretty short work.
For example, your views that AK and RS are rather abstractly "somewhat guilty" have been aired here, and so shot full of holes they resemble Swiss cheese. If possible, the notion that this recent video is either 50% Knox, or 50% not Knox, is so random and speculative - and unscientific - it is barely worth considering. Do you not see that Sherlock Holmes, "himself," demands critical thinking that holds up to substantially more solid evidence, contemplation and rigor?
