Roche worries Armstrong furore may spark witchhunt

Stephen Roche has cautioned against finding people “guilty through association” in the wake of the United States Anti-doping Agency’s scathing reporting into Lance Armstrong.

Armstrong refused to cooperate with USADA, who published a 1,000-page report last week which concluded the Texan and his United States Postal Service team ran “the most sophisticated, professionalised and successful doping programme that sport has ever seen”.

Team Sky, home of Tour de France winner Bradley Wiggins, have reiterated their zero-tolerance stance and will sever ties with anyone with a history of doping.
