Does anyone here seriously believe Bin Laden is still alive? Why are these tapes posted as fact when circumstantial evidence points strongly to him having dies in December 2001?
At the very least it should be entertained that they may be fake.
Yes, I imagine some do. The U.S. MSM continue to act as if he is alive and the various messages that keep popping up are likely to be from him. That, for a lot of people, represents the normal point of view, from which any deviation, however well supported, is suspect. (See the Wikipedia article on ObL for the sad results of this phenomenon.)
Like the mainstream media supporting the "Saddam Hussein Weapons of mass destruction" line. Well that turned out to be true, so no problem there.
