If you haven't noticed it already, you're getting a closer look from police and you enter and move through the subway system and the streets of Washington. Law enforcement have been preparing for the 10th anniversary of the September 11th attacks by increasing their security profiles. That includes airports, train stations, nuclear plants and major sporting arenas. Counterterrorism officials have not indicated there is any credible threat, but they recognize the event is a big target date for terrorists.
