Anti-doping officials of the USA and the UK have various attitude to athletes that have ever taken steroids

2 runners who have served suspensions plan to manifest that they have ability to win without application of steroids. They want to participate in the 2012 London Olympics. Justin Gatlin, an American sprinter, and the British runner Dwain Chambers want to show that they may win, competing clean.
They have already displayed that they are worthy to be called “Olympic champions”. While Justin Gatlin has won the gold medal, Dwain Chambers has won the bronze medal in the 60 meter sprint a1t the 2012 World Indoor Athletics Championship in Turkey.
Justin Gatlin was invited to professional sports again by the USA Track and Field and the US Olympic Committee. 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 participate in the Olympics. This sprinter was not so supported, as Justin Gatlin was. Chambers experienced cold response from the British Olympic Association (BOA). His return to sports prompted the decision of the BOA to suspend sportspersons that have been caught administering steroids from the Olympics forever.
The World Anti-Doping Agency has warned the BOA that this rule didn’t meet criteria the WADA laws connected with prohibited preparations. 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).
so, while Gatlin was supported by the US Olympic Committee, Chambers’ case was not pleasant.
Justin Gatlin has never acknowledged that he had used steroids knowingly. But Chambers took the full responsibility for intake of steroids.
Gatlin 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 8 years. Later his suspension was reduced to 4 years due to cooperation with the USADA.
Justin Gatlin didn’t admit that he had utilized steroids knowingly. He blamed his masseuse for application of a testosterone cream during a massage.
On the contrary, Dwain Chambers admitted that he had administered steroids and taken the entire responsibility for the violation of steroid rules. He was banned for 2 years. This athlete lost all medals he got since 2002.
Different attitudes to these sprinters have manifested the difference between perceptions of sportspersons who have administered steroids by anti-doping officials in the USA and in the UK.
