NBC News is reporting that the Bush administration raised the terror alert level two years ago after CIA analysts mistakenly believed they saw coded messages on the Arabic television channel Al Jazeera. The CIA thought they had decoded a message that indicated attacks were planned on the White House, the Space Needle in Seattle and a small town in Virginia called Tappahannock — population 2,000. In response, the Department of Homeland Security increased the threat level from yellow to orange. Several international flights were cancelled and seven men with Arab-sounding names were detained and questioned in Paris.
