Perhaps that was bin Laden's undoing. He could have stayed holed up in the mountains but noooooo............he had to buy a mansion near a golf course.
He's not the first man to be undone in this manner.
Joking aside, given Osama´s health (kidney) problems, it is likely that the (very) close location of two major hospitals is a factor in the location of the hideout.
Of course, it´s not likely that he was undergoing treatment so close to major military installations without the knowledge of the Pakistani military and intelligence services.
