A Pakistani shepherd looks on while leading his livestock along a road in Abbottabad, Pakistan, April 29, 2012. One year since U.S. commandos flew into this army town and killed Osama bin Laden, Pakistan has tried to close one of the most notorious chapters in its history. The compound that housed him for six years was razed to the ground, and the wives and children who shared the hideaway were flown to Saudi Arabia just last week.
