We were at code red after 9/11 and none of what you suggested happened. Shopping centers stayed open, transportation continued to transport, etc.

Actually, right after 9/11 when we really were at 'code red', air transportation was halted and other transportation severely affected.

I really don't expect us to raise the threat level to 'code red' but only because we probably won't have that level of specific warning before an attack. If they do raise it to 'code red', most of us will be stuck (gladly) staying home and watching events play out on TV.
