More likely, but no more attractive for the likes of the ISI, is that at least some in power in Pakistan knew that Mr bin Laden had been forced by American drone attacks to shift from a mountain hideout to this urban shelter. On this score Mr bin Laden (and probably others, such as the Aghan Taliban leader, Mullah Omar, who was reported earlier this year to have been taken by the ISI to Karachi for medical treatment following a heart attack) was being afforded some measure of protection by Pakistani officialdom. Why? Perhaps so that he could be used, one day, somehow to promote Pakistani interests among fighting groups in Afghanistan, or perhaps so that he could be used as leverage over the Americans on a “rainy day”, as one Afghan intelligence officer speculates.
