As was stated earlier, it has kind of been a sidebar to the story that it would be very difficult to run these kind of times while starting at the back of the back. I'm going to state my opinion that in the larger races, it wouldnt be very difficult, it would be nearly impossible.
Next time your at a crowded stadium for a sporting event, try to make good time walking fast through the crowd...its just not reasonable to believe that this can occur. Sure its no smoking gun, but combine this with all of the other evidence and it helps to paint the picture even clearer. We have now uncovered photographs of KL running sideways across the running path...essentially this would mean that he is running farther than the set race distance. This would imply that he was running even faster than what his times show.
I hope the evidence continues to mount, it really has went from a story of someone cutting some corners, to bordering on pure insanity.
