I am all for Jeb Bush doing what is within his *legal authority* to save Terri.
"if you saw John Couey raping and murdering her, and you could use deadly force to stop him, would you,"
Yes, I would, but I would also submit to judgement of the law on what I did, ie, consider it civil disobedience. But understand that while that is legal in most states, in places like Britain, they've convicted people of murder when they defended their homes against criminal intruders.
What I *wouldnt* do if I was say a DA would be to break the law (eg plant evidence) to get a guy convicted of rape I knew was guilty so he didnt rape again. Maybe restraint would lead to some injustice (ala OJ Simpson), but executive agents of Government abusing their authority is a dangerous precedent that would lead to more harm than good.
The law sometimes is an ass. Rather than challenge the law, we need to challenge our imperial courts and those who presume to misapply the law for unjust ends.
