Dwain Chambers was not supported in his return to professional sports

2 sprinters who have served bans want to display that they may win without application of steroids. They desire to participate in the 2012 London Olympics. The American runner Justin Gatlin and Dwain Chambers, a British runner, want to display that they may win, competing clean.
They have already displayed that they are worthy to be called “Olympic champions”. While Justin Gatlin has obtained the gold medal, Dwain Chambers has received 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 noted about their attitude to this runner, supporting him.
When it comes to Dwain Chambers, it is not clear yet whether he will be allowed to participate in the Olympics. This sportsperson wasn’t so supported, as Justin Gatlin was. Chambers received cold response from the British Olympic Association (BOA). This runner’s comeback to sports induced the decision of the BOA to suspend sportspersons that have been caught taking steroids from the Olympics forever.
The World Anti-Doping Agency has informed the BOA that this rule violated the WADA rules related to prohibited 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 Justin Gatlin was supported by the US Olympic Committee, Chambers’ case wasn’t pleasant.
Justin Gatlin has never acknowledged that he had applied steroids intentionally. But Chambers took the whole responsibility for steroid use.
Justin Gatlin tested positive for testosterone in April 2006. The world record of this athlete was annulled after the results of testing had been proclaimed. At the beginning Justin Gatlin was suspended for eight years. Later his suspension was reduced to 4 years because of cooperation with the USADA.
Justin Gatlin didn’t admit that he had administered steroids intentionally. He blamed his masseuse for application of a testosterone cream during a massage.
On the contrary, Dwain Chambers acknowledged that he had utilized steroids and taken the whole responsibility for the violation of steroid laws. He was sentenced to 2-year ban. This sprinter forfeited all medals he received since 2002.
Different attitudes to these runners have manifested the difference between perceptions of sportspersons who have utilized steroids by anti-doping officials in the USA and in the UK.
