So, just wanted to poke my head in for a moment. The gentleman is retired as far as I understand, and so is a private citizen. This makes his statement completely a matter of opinion which will have no effect on a sentence/criminal matter being faced by someone.
If on the the other hand, he were still a member of government, he would be the director of an executive agency. The judicial branch has authority of determining guilt and sentencing convicted persons (although the Legislature can and does regulate sentencing generally). In other words, even in this event, his statements would have absolutely no bearing on anything, particularly as it pertains to sentencing (to wit: a hanging).
Also of note, the treason part is one of my favorite parts of the Constitution. I mean, "corruption of the blood"? Awesome (ps. that means that there can be no crimes which affect the rights of your blood relatives; which is a pretty smart concept, and especially smart when considering the political climate many of he Founding Fathers/Mothers had come from)...
But I digress. The fact that a private citizen said this is absolutely and completely meaningless. Just as meaningless in fact as the many people on this forum who are saying unpleasant things about the gentleman in question.
