George W. Bush slips up, or does he?

Former US President George W. Bush slips up when talking about the 911 attacks, or does he?

"He told us the operatives had been instructed to ensure the explosives went off at a point high enough, to prevent people trapped above from escaping."

They have to disclose this stuff to us, whether they do it through TV, movies, or freudian slips like this. News readers do it all the time.
