Video and photos of people being forced to jump to their certain deaths to avoid being roasted, and crammed into windows for gasps of breathable air was the reality of 9/11. Showing it would serve the same purpose as the film reels of burning ships at Pearl Harbor did.
It would force those who refuse to a accept reality to be confronted by it, and to galvanize the will of the rest of us.
Did the Pearl Harbor reels show charred and mutilated bodies?
