I'm going to read his posts as a Charlie Brown adult speaking from now on. Like nuking the site from orbit, it's the only way to be sure.
Personally, I have a hard time regarding this event with anything but pessimistic relief.
I doubt that Osama Bin Ladin was even in the top ten most evil men in the world. Certainly, however, he was among the top most hated by US Americans. And with good justifications. The weight of tragedy bestowed upon the world by his schemes, and our reaction to them, is certainly far in excess of the power that should be granted to any man, casting the evils he has perpetrated into a harsh light with long, far reaching shadows. Those shadows will extend long after his flesh is consumed and the light faded.
