blacksheep --- It is against federal law to stir up suspicions of any kind that could incite riot or fear within the air port surroundings , so it doesn't surprise me that nothing was mentioned while boarding a flight . If you don't believe me just say the word bomb next time and watch what happens . I know for sure there were public information warnings on terror attacks years before the bush administration .
I think the clinton administration was more worried about covering their own backs than national security . Especially after the book Unlimited access came out by Gary Aldrich who was in the secret service and he exposed the clintons for the lack of security within the white house itself .
