... as you mentioned with the Anthrax warning signs.
We also know these terrorists might be "Arabic" with colored hair, clean shaven, etc, etc.
I respect to bombings, what did we leave from the Atlanta Olympic bombing? Watch out for people leaving breifcases/packages in public areas? What else? Do you see what I am getting at? We as a nation are sorta naive about terrorism because we haven't had to deal with it before on our soil.
