Why the November Bin Laden Video Was a Hoax

Link.

The Bin Laden tape of last week was clearly a cheap fake. My proof is very simple, as a devout and devoted ultra-fundamentalist Wahabi Muslim, Bin Laden does not believe in kings, queens, princes or princesses. Thus, when this alleged “Bin Laden” called Zarqawi,
“the prince of Al Qa’eda”—it shouted, this is not Bin Laden. Bin Laden would never use these words, but some Hollywood or Pentagon or State Department hack might think it sounded good, as praise for Zarqawi. But in the very doing of this, it made clear that this tape was not Bin Laden.

So why was this tape made? Obviously to be shown to the gullible American public.
Of course it’s always backed-up by the State Department and other American “experts” who claim the voice is definitely that of Bin Laden.

Quite likely bin Laden is dead, and the government is "keeping him" alive, because they find him very useful.
