And if you read Amendments Five and Six of the Constitution, the state ONLY has the power to take someone's life if there is a grand jury indictment AND if the person is convicted by a jury.
Terri WAS NOT charged with any crime, therefore the state DID NOT have the constitutional power to take her life.
But, they did anyway. This is possible only because the hospitals are an institution of the state in the same department as the courts and justice. Doctors are officers of the state just like prison wardens. This went through the courts, and we are perhaps blinded since no crime was charged. The power has nothing to do with crime against the state, it exists on its own.
