Excellent point.
I half expect them to stop temporarily until they evaluate the threat of the drone. In the meantime, I figure they may pass on the duty to a cell elsewhere. I figure it may take the weekend for them to confer and set up. By Monday I expect a sniper to be active again somewhere.
I saw on the idiot box (television) last night that Radio Shack in No. VA was sold out of police scanners. Bright local citizens are trying to determine what's going on without relying on PC spokespeople telling then half-truths.
