Who Was Hiding bin Laden in Abbottabad?

The small Pakistani city where Osama bin Laden is thought to have lived since 2006 and where he died May 2 is sometimes compared to West Point, N.Y., since both cities have military academies. But Abbottabad is more like the less-accessible Colorado Springs, Colo., home of the U.S. Air Force Academy. While a secure and peaceful mountain town seems like an unlikely place to find bin Laden, Abbottabad has long served as a militant transit hub. But geography does not explain why al Qaeda chose it as such, or why bin Laden risked living in the same place for so long.
