For one thing, we're approaching elections. It could cause problems for the Bush-friendly candidates if word of this was suddenly to spread like wildfire through the mainstream media, and people actually started asking some good hard QUESTIONS about it, for once. But that won't happen, because the vast majority of people are sheep who have been drugged into believing the "Bush good, terrorism bad" message that's already been hammered into their brains.

For another thing, Osama makes a great boogeyman to haul out from time to time, to instill fear into the masses and make them beg for yet more big government, civil right shredding measures to protect them from the bad guys.

I could go on and on and on, but I'll spare you and your readers. :)
