The August 2001 Warnings
Now that the full text of the August 2001 warning message to the President has been released, it is obvious there was little the administration could have done-under existing law,rules,and regulations-to have stopped the 9/11 attacks.
The warnings are vague in the extreme,and are on a single sheet of paper.
They mention al-Qaeda presence in the US since at least 1997-but-other than making a note of it,mention no action being taken to roll up the bastards. (They probably couldn't, the way laws and policies were structured at the time.)
Hijacking concerns are mentioned-and it is a fact repeated warnings
were sent to the airlines-by the FBI and the FAA. It is also a fact these warnings were largely ignored.
