Pressure is NOT going to crush it like a tin can. That is bad science. You also DO NOT open doors or windows in a tornado and or hurricane. You will compromise the entire structure.

Good question. In LA during the Rodney King riots, the National Guard was deployed without ammunition. They couldn't find the key to the ammo or something.
