Just a broad shot in the darkness of tin foil, wasn't Falls Church one of the hubs for the DC snipers?
Yes, they were scouting Falls Church for several days and finally shot the FBI employee there. Also Falls Church is the nexus of Virginia Wahabbism; many of the CAIR/AMS/WAMY leaders are in Falls Church (sometimes their offices); many of the 9/11 hijackers obtained their phony VA ID cards from a Falls Church broker (who normally supports the Honduran illegal alien community of Bailey's Crossroads); and of course Falls Church was the former home to several bin Laden brothers.
And with all that, you'd be surprised to know that most of Falls Church is a nice, upscale town with excellent schools.
