It is only elevated when a rumor of a bridge is going to be blown up or some symbolic anniversary comes up. But when actual terrorist bombings and acts are taking place...the colors do not move. This is what makes part of this war on terror look not only silly in context...but downright embarrassing. Get rid of this crayloa chart for morons and announce a REAL threat system that actually is worth a damn. I am insulted to look at this thing and think as an American it is supposed to tell me how scared or calm I am...
