Rusty Hardin presented 4 pictures of Roger Clemens that display lack of physical changes in him

Each baseball fan knows 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, the defense attorney for Roger Clemens, claimed that Roger Clemens’ physical appearance didn’t change greatly before, during and after his trainings with the trainer Brian McNamee. He confirmed that this aspect proved that Roger Clemens hadn’t administered performance-enhancing drugs.
Changing in muscle mass is often used by federal prosecutors as proof that a person applied steroids or/and other performance-enhancing drugs. But this tendency was not used during the governmental case against Roger Clemens. Nobody could affirm that muscles of Roger Clemens demonstrated that he had used steroids and HGH. It is one of differences between the case against Roger Clemens and that against Barry Bonds.
As for the governmental case against Barry Bonds, federal prosecutors called many persons in the trial that could testify that anabolic steroids promoted essential changes in physical appearance of this person. They affirmed that administration of steroids caused enhancement of muscle size, increased size of the head and shrinkage of testicles in Barry Bonds.
So, the defense attorney Rusty Hardin presented 4 photos of Roger Clemens. The photos manifested physical appearance of Roger Clemens, including the time when Clemens was working with Brian McNamee. Hardin pointed out that the pictures showed that there were no changes in physical appearance that could manifest that he administered steroids and HGH.
The defense attorney for Roger Clemens noticed that the photos displayed only the process of ageing. The masseur Cheryl Redfern noticed that she didn’t observe any changes in physical appearance of Roger Clemens. Roger Clemens experienced neither back acne, nor abnormal development of breast tissue, nor essentially increased muscle mass.
Phil Garner, a former baseball player, also claimed that there were not any obvious changes in physical appearance and performance of Roger Clemens during working with Brian McNamee.
Steve Durham, the Assistant US Attorney tried to discredit the affirmation about lack of changes in Roger Clemens’ physical appearance during the cross-examination of the former baseball player Phil Garner. He noted that while several steroids increased muscle mass, others didn’t induce getting muscles. Thus, he claimed 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 claim that physical changes in Barry Bonds manifest that he has utilized steroids, lack of physical changes in Roger Clemens doesn’t prove that he hasn’t administered steroids.
