Two consumers of steroids that have already served their bans want to compete at the 2012 London Olympics

2 runners who have served suspensions desire to show that they may compete successfully without steroid use. They are going to participate in the 2012 London Olympics. Justin Gatlin, an American sprinter, and Dwain Chambers, a British runner, desire to demonstrate that they can win, competing clean.
They have already manifested that they are worthy to be called “Olympic champions”. While Justin Gatlin has obtained the gold medal, Dwain Chambers has obtained the bronze medal in the 60 meter sprint a1t the 2012 World Indoor Athletics Championship in Turkey.
The USA Track and Field and the US Olympic Committee invited Justin Gatlin to professional sports. These two organizations reported about their attitude to this sportsperson, supporting him.
When it comes to Dwain Chambers, it is not clear yet whether he will be permitted to compete at the Olympics. He was not so supported, as Justin Gatlin was. Chambers experienced cold response from the British Olympic Association (BOA). His comeback to sports induced the decision of the BOA to ban sportspersons that have been caught applying steroids from the Olympics forever.
The World Anti-Doping Agency has warned the BOA that this decision violated the WADA rules linked with forbidden products. The BOA decided to fight against WADA and to prevent participation of Dwain Chambers for the United Kingdom in the Olympics. The BOA has taken the case to the Court of Arbitration for Sports (CAS).
Thus, while Gatlin was supported by the US Olympic Committee, Chambers’ case wasn’t pleasant.
Justin Gatlin has never acknowledged that he had administered steroids knowingly. But Chambers took the whole responsibility for administration of steroids.
The American sprinter tested positive for testosterone in April 2006. His world record was annulled after the results of testing had been reported. At the beginning this runner was banned for eight years. Later his suspension was reduced to 4 years because of cooperation with the USADA.
Justin Gatlin didn’t acknowledge that he had used steroids knowingly. He demonized his masseuse for application of a testosterone cream during a massage.
On the contrary, Dwain Chambers acknowledged that he had applied steroids and taken the complete responsibility for the violation of steroid laws. He was banned for 2 years. This runner lost all medals he received since 2002.
Various attitudes to these sprinters have manifested the difference between perceptions of sportspersons who have used steroids by anti-doping officials in the USA and in the UK.
