I've read that Novitsky is a "hard nosed investigator" so I hardly think that LA's comments witch hunts is likely to endear himself to Novitsky. One can only imagine what Novitsky thinks.... frothing at the mouth "ME?? engage in witch hunts??? I will decide the direction of this investigation Lance Armstrong, not YOU".
Also, regarding the alleged positive test in 2001. If this is true, then it should be possible to go directly to the source and trace the results back to the laboratory. If there is a cover up all the way to the lab technician who falsified the records to show a negative result in the database for example, one would expect a paper trail to exist somewhere. If that allegation can be proven to be true, then it means Lance lied under oath in the 2005 SCA case and he will end up in the same place as Marion Jones.
