There were a lot of caves and caverns that al Qaida and the Taliban were hiding in, that have been collapsed by American ordnance. Thousands of tons of rubble are sitting on top of bone fragments that will probably never be uncovered, in about 100 different caves. Some of those bone fragments may contain the DNA of Osama bin Laden. There’s no way to know.
But if you ask an expert, you’ll learn that it’s pretty much impossible for bin laden to be alive. They’d have to keep moving him because we are actively searching for him. Also, he needs kidney dialysis on a regular basis. This means an ever expanding group of guards, car drivers, medical people, personal attendants and ordinary civilians who would need to have seen him.
All those people, and not one leak? Not likely.
