Don't be alarmed, Reston Town Center shoppers, the people bombing the bus today aren't actually bombing the bus. They're only pretend bombing for testing purposes.
Nevertheless, don't pry too much into what's going on -- they're with the FBI.
The video will feature footage of someone planting a simulated bomb on a Fairfax Connector bus.
Filming began at 9 a.m. and will continue until about 5 p.m.
