US commandos missed with their first shot a[s] the world’s most wanted man poked his head out of a third-floor room in his fortress, according to US Sen. Saxby Chambliss, the ranking Republican on the Senate Intelligence Committee.
Bin Laden ducked back in, and the Navy SEALS quickly followed and finished the job, Chambliss said in a telephone interview this afternoon.
The job? Try execution.
Much more here.
