WELLINGTON, New Zealand - World Anti-Doping Agency director-general David Howman said Lance Armstrong pursued what appears to be a systematic doping program for a decade "probably with the knowledge" of people who were charged with detecting drug cheats.
Howman told New Zealand's LiveSport Radio on Friday that Armstrong's repeated claim he has never tested positive for a banned substance could no longer be regarded as proof of his innocence.
"What seems to have happened in this particular scenario is that it went on for many years under the noses of those who were supposed to be detecting it and at times probably with their knowledge," Howman told the New Zealand program from WADA's headquarters in Montreal.
