With that logic we should convict anyone who pleads the 5th. Innocent before proven guilty last I checked. You ASSUME he is guilty because he will not testify. And I am pretty sure that if he was put on the stands it would not end up being as cut and dry as: Did you give him steroids? No. No further questions. Most likely the guys credibility would be called into question. Him and his entire family would be scrutinized and it would end up being, even if he said no, spun that he is a long time friend and trainer of Bonds and stands to lose financially if he says he did give him the steroids. A lose lose situation. You mention he is afraid of perjuring himself but don't you think that Bonds would have a team of lawyers in there to defend him and coach him on what to say and what not to say? All on Bond's money. They guy is supposedly one of Bond's best friends and money would not really be an object.
