If this is terrorist work, IMHO we cannot be fixated on the theory that the very same one or two terrorists are going to be out shooting, or that they will stay in the same vehicle or use the same caliber bullets; on the other hand, there are random acts of violence every single day around and in the DC area, so some of these may just be what normally happens but is rarely reported.

I agree.If I was the shooter,I'd be armed to the teeth for a major shootemup with the Police if I was spotted.
