More details coming out: The intelligence that led to the operation originated from captured al-Qaeda detainees more than four years ago. They identified a courier close to bin Laden. Eventually, the courier was located and the compound where he lived found. The courier was one of those killed in the raid.
Obama administration sources said that bin Laden's identity was established by DNA and that his body would be buried swiftly according to Islamic custom. However, I also hear they buried him at sea on the way back to avoid his grave becoming a shrine.
