how? that is the question. simply saying that he is generally in this area, doesn't mean you know where he is with enough specificity to go and get him. Its like saying you are someplace in Parkersburg West Virginia. OK, what do I do next? Its not like OBL just went to DMV for a license renewal or applied for an AMEX card in Pakistan - the kinds of things law enforcement uses to trace people in the US aren't available over there.
Well, that's why I said a very BIG if. Personally, I think it's so hard to find Osama because both he and Elvis use the same line for seances and they keep getting mixed up.
