How Osama Bin Laden was found

As you probably know, Osama Bin Laden was killed inside his compound over the weekend by a US raid. But before killing him they had to know where he was hiding. Osama Bin Laden was the head of a terrorist organization called Al Qaeda. They were the criminals behind 911 which led to Bush's "war on terror" and the eventual invasion of Iraq. Bin Laden had been seen as a threat by the United States long before the events of 911. The US gathered information on him, including his personal couriers. After 911 they went after these couriers, capturing them and interrogating them. In Abbottabad (a city 40 miles from the capital), they found a very strange home.  It was surrounded by walls almost 20 feet tall, had no windows, and more sets of walls inside the compound. Curiously, it had no internet or telephone lines. The US concluded that there was something being hidden inside. They also found out that a family lived inside that matched Bin Laden's. Although there was no proof, analysts were sure Bin Laden was hiding there. A Spec-ops team was assembled for this kill mission (they were not planning on capturing him). A live camera was brought with the team, and when Bin Laden was killed a huge cheer went up from the CIA officials in the conference room.
