A tornado bearing down on you can sound like an onrushing train. That doesn't mean it is one. People's perceptions, especially in panic situations, are worse than useless.

Funny how in the weeks and months before the attack, nobody saw anyone wiring any of the buildings with explosives. Funny how not one of the massive crew of people who must have been involved has developed a guilty conscience and come forward to confess.

Actually it's not - 'cos it didn't happen.
