It seems they are very interested in building an exact paper trail for shirts they asked for a year after the murder but don't show anywhere near such thoroughness in any other matter that is not designed to implicate the Ramseys.

Shoes: Apparently, John Ramsey, like most fathers, has only a vague awareness about his son's shoes but seems to think that he had footwear than had all sorts of stuff on it: lights, compasses, etc.
Query: would you ever refer to this type of footwear as 'hi tech'? Would a nine year old? Particularly if that was a term used by the interogator and the nine year old was merely assenting to it?

Rewards: It is well known that not only would a higher award have been unnecessary and useless, it would have been counterproductive. All LE personnel advise a modest award so as to keep as many of the nutcases who have nothing to contribute from thinking that inventing some weird tip is going to be easier than buying a lottery ticket. I'm not saying that I would necessarily have been suspicous if the Ramseys had posted a million dollar reward, but I would certainly think they had been ill-advised and that the reward was slowing the progress of the investigation by generating false leads.
