No this guy just calmly gets back in his van, bold as the night, and drives off into what can only be construed as a traffic nightmare of cars and lights. No one is carrying a concealed weapon who can make an attempt at stopping him.
People see the guy, but we never hear, was he young, old, was he bald or did he have hair, was it short or long, did he have a beard or facial hair, was he tall or short, heavy or skinny, did he shoot right handed or left-handed, was he wearing a delivery or repair uniform, how was he dressed, did the rifle have a long barrel.
Can they describe the weapon's color, shape, when the van left did it emit white or black exhaust from the tailpipe in a constant stream, what kind of side-view mirrors did it have, what was the shape of the taillights, was the one just out or broken.
At first I suspected a couple of mind-numbed 20 year old dropout computer game geeks off on a new thrill. But the consistent head shots from a distance, and the upper left chest (heart) shots, and the fact that he never feels the need to squeeze off another round, to me suggests a superbly trained, highly confident marksman, perhaps foreign-born and trained, perhaps AQ as part of a sleeper-cell in the D.C. area.
The nearby mosques should be canvassed and searched for any mosque-owned vans, as well as any garages they use for vehicles they own.
I pray this guy is stopped soon. It seems to have no end in sight.
