Let's see, the man was accused of...gasp..."lying to Congress".
Those folks lie, or at least deceive and distort, to each other almost daily-hiding motives, hiding connections, pushing bills for special interests that have donated money, refusing to acknowledge anyone in the opposite party has an idea even worth of spit....and we indict someone...anyone...for "lying" to them? Seems to me Clemens probably did what the congressional folks pretty much do daily.
In medical malpractice cases, doctors don't have to practice perfect medicine, just do what the ordinary physician would have done in the same circumstances. This is called the "Standard of Care". Seems to me Clemens met that. Very sad but true. Integrity is often times hard to find in politics.
How could any jury take seriously a charge of "Lying to Congress"?
