"Might"? Might? This is an important specific to elide; one hopes for a more declarative offering. Never mind. What we already know for a fact indicates that Khan's efforts have single-handedly endangered more human beings than all but a handful of things or people you can even contemplate. This asshole should be on a slab. He should leave his villa feet first. Period.
Further developments only bolster my argument for taking Khan out, and I don't mean for a nice lunch at a café:
I understand the wheres and whys of Musharraf leaving Khan alone; I even understand why we leave him alone. Were we to give Khan his just desserts and dispatch him forthwith, the usually calm and pro-American Pakistani populace would suddenly take a break from gang-raping lower-class women to turn on us and Musharraf.
Nonetheless, I submit that this is a story that should push every other story off the front page, if only to get this matter discussed more proactively. There is no rational reason that an insect like Khan should just be allowed to get away with this as completely as he has. At the absolute minimum, making sure every armchair rube knows exactly who this clown is and what he did would force Pakistan to rethink their protection of him -- they'd at least have to publicly justify it to the rest of the world.
Meanwhile, I guess we just cross our fingers and hope against hope that ol' A.Q.'s handiwork isn't already on its way over here, stashed in the cargo hold of some freighter. Feelin' safer already.
