This is not good.
One of the arbitrators is Clark Griffith. Mr. Griffith recently pled guilty (an Alford plea where he admits the state has sufficient evidence to convict him) to a charge of public nudity while trying to "pick up" one of his students. Salacious details here: http://www.twincities.com/localnews/...twincities.com
Now, this just makes him look bad. However, Mr Griffith was also quoted as expressing at least some opinion of the case, "He's really scrambling .... I can't wait to hear what the arbitration panel thinks of the evidence." http://www.startribune.com/sports/160869725.html
Mr. Griffith, if not biased, is at least an embarrassing choice by the USADA as an arbitrator.
This is a separate issue from whether Mr. Armstrong did or did not use PEDs. The issue is, when the USADA is putting together what may be its most important case, it chose an arbitrator who is an embarrassment and who cannot maintain a judicial demeanor when he is supposed to be fairly arbitrating a case.
