Today was the day of the big C&E gunshow at the showplace on Mechanicsville Pike in Richmond, basically the biggest gunshow in Virginia. It's unlikely but possible that the sniper was down there loading up on ammo or some other supply necessity and simply saw an opportunity for a couple of shots on the way back. The show ended at 5:00 so that is unlikely, however, the gun grabbers will latch onto this if they are aware of the show. The place was more crowded than I have seen in a long time.
