My point in all of this is that sooner or later common sense has to kick in. When it does there is no other way to do this except the way we did it. Screw his "rights". Capture is all but impossible. There isn't anything else. You either have to kill the guy when and where you find him, or let him go. The later would be stupid. I am not buying into all of this "slippery slope" nonsense, in that if we allow the government to do this, the next thing is they'll be assassinating citizens for not paying back taxes, or some such silly, concocted foolishness. When anything even remotely happens like that there are consequences. One only has to look at Waco and Ruby Ridge to see what happens when the government oversteps it's bounds on it's own citizens. And before you again go off on some kind of legal tangent, remember that David Koresh and Randy Weaver did not denounce their country, or plot to kill anyone.
I'm not a civil rights, or constitutional lawyer and neither are you. With that said when an individual denounces his country, then plots to kill it's citizens, and attempts to carry out such attacks more than once, and successfully, (Fort Hood), then all bets are off. If that "fractures" a few of his rights he has, or once had, from a country he has since denounced, too bad. We as a nation have never faced a situation with enemies such as this. Because of it there very well may have to be some new laws enacted or rewritten. Until they are I see no reason to make something dangerous and complicated even more so by ignoring it, and letting someone of this caliber go free. There was no other way within reason to do it, period.
