The Taliban does not exactly equal al Qaeda. If those Taliban did something wrong then it is right to talk to him. Even so, why not question him instead of detaining him?
The Al Qaeda used laptops to compose terror orders, then sent couriers to the West with discs for dissemination of attack orders and plans. Ujaama was clearly one of the Al Qaeda couriers.
Do you think he only thought he was going back and forth with commercial information on Afghan rugs?
Please, we are in a war against islamic terrorists, breathe in a deep dose of reality.
Unless you secretly sympathize with the enemies of the USA, in which case I understand your defending this terrorist courier while pretending not to understand what was going on.
