"Congress had no business with the Terri Schiavo affair..."
You are right. The proper way to rectify a gross miscarraige of justice by the courts is an executive branch pardon.
Either GWB or Jeb could have weighed the facts of Terri's condition and made a decision. They had the legal, moral and force of arms authority to decide this matter. That Florida judge who issued the prior restraint order should have been removed from the bench by force. He had no jurisdiction over the Governor and Jeb was a total milksop to have obeyed the judge.
I would have trusted a decision from GWB much more than from any of the principals who were fighting this in the courts.
What good would that have done. Ms. Schiavo wasn't accused of any crime.
