tl;dr:<p><i>Hersh’s most consequential claim was about how bin Laden was found in the first place. It was not years of painstaking intelligence-gathering, he wrote, that led the United States to the courier and, ultimately, to bin Laden. Instead, the location was revealed by a ‘‘walk-in’’ — a retired Pakistani intelligence officer who was after the $25 million reward that the United States had promised anyone who helped locate him. For that matter, bin Laden was hardly ‘‘in hiding’’ at all; his compound in Abbottabad was actually a safe house, maintained by the Pakistani intelligence service. When the United States confronted Pakistani intelligence officials with this information, Hersh wrote, they eventually acknowledged it was true and even conceded to provide a DNA sample to prove it.</i>
