What is it that you're going for here? What's your motive for arguing? Many of us understand that the possibility of doping hangs over any good performance. You seem to accept Shaheed's time as legitimate. Why? Or am I wrong there? Do you have any criteria for whom you suspect and whom you do not other than your own subjective ideas about how fast is too fast to be believable?
Or put it this way. Imagine for a minute that Barton's time is legitimate. Is there anything that would convince you of that?
