Why? I have a problem with this logic on two basis. First, the idea that a certain quantity is needed. Second, that steps were not taken to keep stuff off the computer. It is possible to download stuff directly to a CD. The fact he had any at all doesn't mean that is all he had.
I don't know much about computers, but it seems to me that someone on another thread sais you can get porn e-mailed to you at random?
I know its possible to have someone send you a picture and not know what it is until its too late and already on your computer. However it takes a special step to save that picture in a folder designed for it and it takes another special step to copy it to a CD. It is certainly possible for someone to unwittingly do this but when the images are viewed 1-5 times, when they are stored in special folders and when they are copied to disk the likelihood is very slim.
This leads to an interesting way of thinking that the Westerfield is innocent crew use. They individually prove that each specific piece of evidence could have an innocent explanation even thougfht the sum total makes it improbable. For example, if I had porn on my computer stored in special folders and copied to CD's and my wife found them I could maybe get away with one or two stroed in a temporary file but if she also found that I accidently viewed each one a number of times and i accidently stored it in a special folder and I accidently backed those files up, she would not likely believe me.
The law pertaining to this trial is that for circumstantial evidence, which ALL of the evidence is, each piece must be weighed individually. This is because it is circumstantial, and not direct evidence. Shall we hang a man because a mountain of circumstance is against him, where each individually has a reasonable innocent explanation? The Law says clearly, NO!
The sum total may seem to make it improbable to us, but in order to protect the innocent victim of circumstance, the Law is such. I remember a poker game that I played, and the stakes were big. I had four of a kind. By all reasonable probability I was the winner -- I reached out for the pot, a happy man. Yet I was stopped. The one player in the game I really disliked threw down his hand and grabbed my arm at the same time. "Read 'em and weep." -- he had straight flush. I was embarassed and cut up wallet-wise. I vowed never again to jack up the bet so high in a game with wild-cards and plenty of beer. My inexperience showed and cost me.
