Someone has mentioned that the van could be a decoy, but I'd like to elaborate on that and suggest the white van as an unwitting decoy.

I've proposed both of these scenarios as possibilities (1. Decoy White/or other color vans, or box trucks (2. Unwitting White vans used as existing camouflage or as you say, 'the green light to shoot).

Another possible scenario is a combination of the two... What if the shooting blind is now a black vehicle providing an enclosed space. They wait for a white vehicle of some kind to appear (with ladder racks or whatever) They shoot. The sniper leaves separately from the van on a bike with the broken-down weapon. Only way to detect this is to smell the inside of each van or truck in the 30 mile area.

This would require safe houses (in Montgomery County, Spotsylvania, and Manassas, that the bike rider could ride to and hole up (or possibly three or four separate cells including Bowie)
