(Via VCDL)
Showmasters has pictures on their website of various law enforcement officials at the Richmond Showmasters gun show (August 13-14, 2005) on their home page. Bravo to Annette Gelles for visually documenting this event for posterity.
G. Gordon Liddy interviewed the CNS reporter who interviewed VCDL (strange, why not interview VCDL directly?), and a MP3 copy of the audio is availablehere.
At this point, I think we can safely rule out the possibility of a hoax.
