Barry Bonds. Guilty on a technicality. At least that's how much of the public sees it. It's all that came out of a seven-year investigation into baseball's home run king. Lance Armstrong. Not even prosecuted. A two-year, multi-continent investigation brought to a close this year with no charges filed. Now Roger Clemens. Acquitted on all counts. A five-year investigation ended with the top pitcher of his generation celebrating with family hugs inside the courtroom.
