I still have major doubts it would take as long as you claim. To be honest it just seems like your trying to make excuses to defend Shawn which is kind of admirable I suppose. I have no idea about child porn but I imagine a file would have hundreds or thousands of pictures in and these could be transferred quickly. Not just that you could make a file of these pictures and email them or send them over msn etc . Did the police say they was specifically downloaded that matter or that they was on the computer?
