It's very important to go back and keep in mind the distinction between handling these events as criminal acts which was the way we did before 9/11 and then looking at 9/11 and saying 'This is not a criminal act ' not when you destroy 16 acres of Manhattan kill 3 000 Americans blow a big hole in the Pentagon. That's an act of war.
Most of the trouble in this world has been caused by folks who can't mind their own business because they have no business of their own to mind any more than a smallpox virus has.
