Torri has a reputation for being uncompromising in the battle against doping, having charged sports personalities in the past even when they argued that their positive tests were the result of accidents.
And as professionals, whose livelihood depended on results, and where testing was either non-existent or a step behind the latest advances in sports doping, it is unsurprising that so many succumbed.
Mr. Armstrong was stripped of his titles last year after the U.S. Anti-Doping Agency, which polices drug use in American sports, initiated formal charges against him for allegedly conspiring to run an organized doping program aimed at dominating the Tour de France.
Landing Armstrong and becoming confessor to the man who for so long looked the least likely candidate in sports to admit to doping is a massive coup for Winfrey.

Last month, the U.S. Anti-Doping Agency banned Dr. Ferrari from working in Olympic sports for allegedly administering performance-enhancing drugs to cyclists when he was acting as a training consultant to cyclist Lance Armstrong during his Tour de France wins.

He stands accused of lying about it of defrauding us, in his testimony before a grand jury investigating high-level sports doping, about the nature of his greatness.
The data collected will then be used to develop action plans for the sports federations and ultimately to increase compliance with the International Convention against Doping in Sport.
In his meeting with Travis Tygart of the US Anti-Doping Agency, Armstrong apparently whined about being singled out, pointing to the fact that sports in general football, baseball are rife with drug cheaters.
International Tennis Federation (ITF) president Christian Bimes said doping was taking place but was quick to point out that it was not as widespread as in other sports.
That's in part because Armstrong is the first athlete to face a serious doping case without losing his popularity, and in part because his popularity is invaluable to the attention-challenged sports he favors.
The U.S. Anti-Doping Agency has developed a "True Sport" campaign to help parents, coaches and administrators return the emphasis in sports to the life lessons that don't show up in the won-loss column.
