i cant agree more about the credibility part of it, but the RDs wont DQ him without proof
remember what the Missoula guy said (from 2nd Litton thread):
"Given all of the work I did, it is my opinion that all of this speculation about his splits for various segments of the marathon courses do not constitute very strong evidence for cheating.
Taken together, however, his gun/chip differential, his weird splits, his changing clothes and a few other things make one very suspicious, but again, they aren't a slam dunk. For this reason, the race directors that I contacted at Providence and Vermont City were unwilling to disqualify Litton. The race director at Delaware WAS willing to disqualify him because in addition to the above items and a complete lack of race course photos, Litton had literally changed clothes and shoes during the race and done a few other suspicious things.
For me, the most important piece of real evidence that he has cheated in so many marathons is that in starting at the back of the pack, two to six minutes behind the runners on the front line, he literally has to pass almost everyone to finish near the front. This leads to the following: no evidence is stronger than the fact that none of the runners that finish near to Kippy but behind him recall seeing him on the course - NONE." - http://kiplitton.blogspot.com/2011/01/discussion-on-disqualifications.html
