How does anyone think we found Bin Laden? We got at him by triangulating phones, some taken of Hassan Ghul, a currier and ranking officer in Al Qaeda. He was captured by Kurdish forces and handed to us in 2004.

Is market penetration in China that thorough? I thought the Muslims lived in the mountains, in Tibet/Western China. Generally rural and I would have thought it would require a lot of cell phone towers.
I could be wrong about that.
