On the subject of Ashenden, he said that he hasn't actually seen the Armstrong data that USADA have. Now either he's playing with words or he's not one of the experts in the USADA case. That would surprise the hell out of me given his standing and experience but it makes sense if you consider that Ashenden is pretty much on record as saying 'Armstrong doped' from having reviewed Armstrong blood data before. USADA may not want to risk having a witness who's testimony can be called into question despite their expertise in the field.
