I'm quite certain that certain factions within Pakistan were both hiding and supporting him, while others were helping the United States. For the U.S. to conduct that strike required Pakistan's support. On the other hand I'm sufficiently cynical in this situation to say that likely the self-same group did both (support Bin Laden, *and* hand him over). (And yes, I also agree with the charge of incompetence. None of these things are mutually exclusive.)
