The 12th anniversary of 9-11 is Wednesday, and the date has always been a cause for concern.

Would terrorists use the date to make a symbolic statement through some form of violence.

While U.S. officials are aware that al-Qaida is committed to attacking targets in the west, the F-B-I and Homeland Security say there is no specific threat this year, and no information that points to plots tied to 9-11.
