I'm no legal scholar, so I don't know what all he could have done at the point at which Terri was being put to death. But if he's responsible for signing into law the piece of legislation which led to her death, how can he reconcile his words with his deeds? And pardon me, but the italicized text is BoBo speak, if you ask me.
Jeb Bush is not a legislator or a judge. He is an executive. An executive's function is to ACT, and to oppose the other two branches of government if they commit a crime, which is what the judges were doing when they ordered the murder of Terri. He chose not to act, instead attributing infinite power to a probate judge in some swamp.
