Now, what's wrong with using Washington? Or Alexandria? Oh, and remember that you have to give the SWAT team 24 hours notice about the drill.
Given a little more thought on this, we also spend far too much time on airports and nuclear plants - People, any half-smart terrorist is going to realize that the worst they can likely do with a nuclear plant is SCRAM it such that it isn't going to be making power for a while. You CAN'T make a modern nuclear plant go boom - there are too many safeguards in areas that even a suicidal terrorist isn't going to last long enough in to make a major radiation release possible.
Airports, of course, have lots of security.
Attack them? Nah... it's already been done. Besides using a home-brew derailer to knock trains containing dangerous chemicals off the tracks around inhabited areas, I'd go after chemical plants and petroleum refineries. Much more bang for the buck, so to say. Safer too.
So air travel is already unsafe - now roads(due to chains and IEDs), and rails are unsafe as well. Work's not safe either(I'd have them hit up the occasional business as well).
The whole idea is to turn us into a bunch of whining cretins afraid to go out of our homes*. Make us feel unsafe, etc...
That and a single two man team, with a two man support element, working a 'leisurely' if at odd hours, say 40 hours a week. Don't want to wear them out... That's 160 man-hours a week. We'd put more than that in in the first HOUR after an attack - the very goal of asymmetric warfare.
*Heck, a few home invasions, kill everybody in the house, then leave would remove even that.
