While Justin Gatlin was supported in his comeback to professional sports, Dwain Chambers met another treatment

Two runners who have served suspensions plan to display that they have ability to compete successfully without usage of steroids. They are going to take part in the 2012 London Olympics. Justin Gatlin, an American sprinter, and Dwain Chambers, a British sprinter, desire to show that they can win, competing clean.
They have already shown that they are worthy to be called “Olympic champions”. While Justin Gatlin has received the gold medal, Dwain Chambers has won 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 athlete, supporting him.
As for Dwain Chambers, it is not clear yet whether he will be permitted to compete at the Olympics. This sportsperson was not so supported, as Justin Gatlin was. Chambers received cold response from the British Olympic Association (BOA). Chamber’s comeback to sports prompted the decision of the BOA to suspend athletes that have been caught taking steroids from the Olympics forever.
The World Anti-Doping Agency has informed the BOA that this rule didn’t meet criteria the WADA laws linked with banned drugs. The BOA decided to war on 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).
so, while Gatlin was supported by the US Olympic Committee, Chambers’ case wasn’t pleasant.
Justin Gatlin has never acknowledged that he had taken steroids intentionally. But Chambers took the entire 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 pronounced. At the beginning this athlete was suspended for eight years. Later his ban was reduced by half because of cooperation with the USADA.
Gatlin didn’t acknowledge that he had utilized steroids knowingly. He demonized his masseuse for application of a testosterone cream during a massage.
On the contrary, Chambers acknowledged that he had taken steroids and taken the entire responsibility for the violation of steroid laws. He was sentenced to 2-year ban. This sprinter forfeited all medals he got since 2002.
Various attitudes to these sprinters have shown the difference between perceptions of sportspersons who have used steroids by anti-doping officials in the USA and in the UK.
