Prosecutors’ tendency to use changes in physical appearance as proof for usage of steroids can’t be used in case against Roger Clemens

It is known by each baseball fan that Roger Clemens is accused in obstruction of justice. It is believed that he has lied before Congress about intake of steroids and HGH.
Rusty Hardin claimed that there was no any difference in physical appearance of Roger Clemens before, during and after his working with the coach Brian McNamee. He affirmed that this aspect was a proof that Roger Clemens hadn’t applied performance-enhancing drugs.
Enhancement of muscle mass is often used by prosecutors as proof that a person administers steroids or/and other related drugs. But this tendency was not used during the governmental case against Roger Clemens. No one could claim that Roger Clemens’ muscles demonstrated that he had used steroids and HGH. It is one of differences between the case against Roger Clemens and that against Barry Bonds.
When it comes to the governmental case against Barry Bonds, prosecutors called many individuals in the trial that could testify that anabolic steroids promoted essential changes in physique of this sportsperson. They confirmed that application of steroids led to increase of muscle size, increased size of the head and testicular atrophy in Barry Bonds.
So, the defense attorney Rusty Hardin showed four pictures of Roger Clemens. The photos displayed physical appearance of Roger Clemens, including the time when Clemens was working with the coach Brain McNamee. Hardin noted that the photos manifested that there were no changes in physical appearance that could manifest that he applied steroids and HGH.
The attorney Rusty Hardin confirmed that the pictures displayed only the process of ageing. The masseur Cheryl Redfern noticed that she didn’t observe any changes in physique of Roger Clemens. Roger Clemens experienced neither back acne, nor gynecomastia, nor dramatically enhanced muscle size.
Phil Garner, a former baseball player, also claimed that there were not any essential changes in physical appearance and performance of Roger Clemens during working with the trainer Brian McNamee.
The Assistant US Attorney Steve Durham put efforts to discredit the argument about lack of physical changes in Roger Clemens during the cross-examination of Garner. He noted that while several steroids increased muscle mass, others didn’t induce gaining muscles. Thus, he confirmed that the pictures could say nothing about steroid use.
Federal prosecutors want to take advantages in both cases: in the case against Roger Clemens and in that against Barry Bonds. While they confirm that physical changes in Barry Bonds manifest that he has taken steroids, lack of changes in physical appearance of Roger Clemens doesn’t prove that he hasn’t applied steroids.
