Re: Now Landis is challenging his test results ...
Nice try, but not a good analogy. Arabs can't exactly help being Arabic, i.e. they don't get up one day and say "I think I'll be Arabic today".
Marion Jones gets up every morning and decides "I will compete under the IAAF rules today".
She is not obliged to do so, anytime she wants to she can drop into the local Piggly Wiggly and get a job bagging groceries.
On the other hand, every day she gets up and decides to be an athlete is a day she accepts the rules and regulations of the IAAF, including the fact that she might be suspended on an accusation which may or may not be proven at a later date.
Like it or not, those are the rules she chooses (note that word) to play by.
I certainly did think you were soft on drug cheats, in fact I bet you'd be tougher than I am (I honestly don't feel terribly strongly about it) but don't confuse the rules you choose with the rules you don't.
