And Pakistan did not know?

2.  More now on the intelligence that led the US to Bin Laden. A senior White House official described the compound where the al-Qaeda leader lived: "We were shocked by what we saw - an extraordinarily unique compound. It is roughly eight times larger than the other homes in the area. It has 12-18ft walls topped with barbed wire. Internal walls sectioned-off different portions of the compound to provide extra privacy. Access to the compound is restricted by two security gates, and the residents of the compound burn their trash, 
   unlike their neighbours, who put the trash out for collection."
3. The official continued: "The main structure, a three-storey building, has few windows facing the outside of the compound. A terrace on the third floor has a 7ft privacy wall. The property is valued at approximately $1m but has no telephone or internet service connected to it."

1. And the White House official went on: "We soon learned that more people were living at the compound than the two brothers and their families. A third family lived there - one whose size and makeup matched the Bin Laden family members that we believed most likely to be with Osama Bin Laden. Our best assessment, based on a large body of reporting from multiple sources, was that Bin Laden was living there with several family members, including his youngest wife."
