So they found a cache of porn in the stuff taken away from the Osama lair....
One really does not know what to make of that. We could chose the Chavez route and say that all of that is work of the CIA to tarnish the image of Osama, just as they want to tarnish his image with the Reyes computers (one has to marvel at the amount of time, resources and personnel that the CIA would need to have to type thousands of coherent pages just to tarnish someone's image...)
One could say that Osama was simply "documenting" the sex exploitation of the West.
One could also blame it on a bored guard locked up in Podunk, Pakistan.
Or one could more realistically blame it on psychopathic minds that have lost basic notions of good or evil and see no contradiction in using porn while they kill for it. After all, we only need to look at the story of some notorious born again preachers or devoted catholic deacons whose private lives differentiated quite a lot from their preaching to understand that the line between sinning and psychopathy might be thinner than what we would like it to be...
