Bin Laden is a bit more sofisticated than a cave man, as well as the terrorists who perpetrated the atrocity. Also he planned the attack BEFORE 9/11 when he was not hiding in a cave and his organization controlled an entire country called Afganistan where they trained Jihadists from the entire world, many of those came from sofisticated weternized societies such as the UK and the USA. This forum should really impose an age limit.
