I don't know the meaning of the acronym "psc" but according to my sources (who know Central Asia very well) Bin Laden is very likely still around and kicking ass.
So you may disagree with Scheuer, but thinking Bin Laden is dead is very naive.
Also Bin Laden unlike Dubya is an extremely smart persons with a very cunning mind and lives an extremely ascetic life. (He is certainly an extremists but underestimating him or even thinking he's dead is very naive. There are even a few Americans who have personally known Bin Laden, talk to them, they all more or less agree with Scheuer.)
Private Security Personnel, of which I have extreme first hand knowledge of. Many of whom have spent more time on the ground in and about Iraq and Afghanistan than Government troops. Whatever fuels your paranoid dogma, believe what you like. The purveyors of sensationalism will always find an audience and there's always an abundance of ignorant schleps who hang on the media's every word for validation and guidance. Drink up.
