The compound where Osama bin Laden stayed for the last 5-6 years is 8 times the size of the homes around it, has 12-18 feet high walls, barb wire on top and no phone or internet service. It has two security gates.
And no one in the Pakistani government thought to check it out? Also, remember this is in the capital city. Image a compound of this sort built in Washington, D.C. without undergoing FBI scrutiny.
I cannot imagine it and Pakistan has less freedom than we do.
