A good guess, given that Pakistan is probably 99% Muslim.... The question is, whose people did it? Musharraf is not likely -- he has much more to lose from her death than he ever did from her political opposition. The extremists are the real beneficiaries here -- A-Q sympathizers is my guess.
Im Sure Pervez Mush. is curled up in his little bed sleeping gently.
Pastoon guys, or maybe some very light Punjabis, but most likely Waziristani gumbahs.
