The team figured in the need for electricity, ceilings high enough to accommodate his height, spare rooms for body guards and security. That left three walled compounds.
Like out of the television show “Num3bers” the team used mathematical models to theorize that Bid Laden would be close to the last place that he was spotted. They also figured in the need for secrecy. If they are correct the US forces should be going to Parachinar which is only 12 miles away from the Afghanistan border.
The town would be able to support medical needs like the dialysis that Bin Laden reportedly uses.
Using satellite pictures the team even has the location down to one of three houses.
