If this is not extermination, it is extermination by another name, to paraphrase the line about a "rose is a rose is a rose," or however it goes. But Jeb said he is contented because he knows that he did all he could. After Terri's death, I wonder if there will be a hurricane of outrage directed against the governor, who now looks petty, vain, and foolish in some eyes. Right-to-life people who have voted for Jeb Bush in the past will increasingly feel that he has betrayed them.
You have made a good point about state police under Jeb Bush being fearful of clashing with the state judge. Therefore, Jeb should have asked that his brother intervene to overrule the constitutional crisis in FL. Not intervening cedes the power to the judiciary.
I suppose that if Jeb had tried to use pardon power, the state courts would have immediately struck him down on that too.
Maybe the problem is that the FL governorship is institutionally weak, something often said of the TX office as well.
