A bit OT, but Jeff is right about pseudo-authority paraphenalia. There's a little Irish pub in McLean where I occasionally have lunch. There used to be a sporting goods/trophy shop a couple doors down that did the uniforms for the 'Christians In Action" intramural softball teams over at Langley, plus they also sold very official looking caps and t-shirts for the FBI, INS, DEA, et al.
If you want ot have some real fun, try going in the back door of a big restraunt with an INS ball cap and jacket on & watch how fast the kitchen clears out
