"What we want is that our Olympic athletes and Olympic champions are heroes, not just winners", said Dick Pound, a longtime IOC official. Pound, who will head a new commission charged with reducing the size and cost of the Olympics, told a Montreal news conference that 2,500 out-of-competition tests have been conducted on athletes from 75 countries, with 24 possible positive results showed actual use of illegal drags. Pound said his World Anti-Doping Agency is creating the conditions for dope-free sports. The eventual goal is a single global anti-doping code embraced by the IOC and the governments of Olympic countries, Pound said. Such a code could be in place in time for the 2004 Games in Athens, he said. "We'll be able to find anyone we need to find wherever they are, anywhere in the world", he said. "That is going to give other athletes who don't cheat a greater confidence, that there is no cheating going on. At that stage, our role switches over from testers to observers", he said.
