Federal government is disappointed about Roger Clemens’ case

The desire of the federal government connected with the case of Roger Clemens was following: they desired to prove that this athlete had lied before the Congress about application of anabolic steroids and HGH. But the government couldn’t do it. It was expected that Andy Pettitte would say that Roger Clemens had admitted that he had applied the prohibited drugs during a conversation in 1999 or in 2000. But the testimony of Andy Pettitte was shocking for prosecutors. This man claimed that he couldn’t confirm that Roger Clemens had used steroids and HGH because he was not sure.
Actually, why were the prosecutors shocked by the affirmation of Andy Pettittte? This person swore for the 2008 Congressional hearings on administration of steroids in the Major League Baseball that Roger Clemens admitted to intake of HGH. But he pronounced opposite testimony at the Barrett Prettyman Federal Courthouse in Washington.
Michael Attanasio, a defense attorney for Roger Clemens, asked Andy Pettitte whether he may say that he is 50-50 that he has misunderstood Roger Clemens about HGH. Pettitte answered that he is really 50-50 about this factor.
When the prosecutors heard Pettitte’s answer, they became confused. They stated that Pettitte never said this way, when he was asked certain times.
The judge Reggie Walton claimed that he understood that Andy Pettitte’s answer has been conflicted. Actually, his statement was following: “I don’t know”.
The attorneys for Roger Clemens used the moment of the federal prosecutors’ embarrassment. They requested the judge to ignore the testimony of Andy Pettitte because he was 50-50. The attorneys concluded that he probably misunderstood Roger Clemens or he forgot the details of the conversation.  
The government has noticed that the jury still allows taking into account the affirmation of Andy Pettitte. ASUSA Dunham has pointed out that under federal laws jury is allowed to choose which testimony to believe. This person hopes that the jury will brush aside the testimony that doesn’t support the government.
So, the testimony provided by Andy Pettitte and his wife led to problems. Testimonies of Andy’s wife during the first trial resulted in the declaration of a mistrial by the judge Walton.
Pettitte confirms that he is Roger Clemens’ friend. Clemens must also claim that they are friends after the last testimony of Andy Pettitte.
