It's OK to overreact to shootings in Washington - The Week

It's OK to overreact to shootings in Washington - The Week: The Secret Service, Capitol Police, Park Police, and Washington, D.C. police have prepared and rehearsed for all sorts of unknown troubles; the biggest X factor is simply trying to respond proportionately when there is no way of knowing what is actually happening; whether one event is connected to another, or whether others are yet to come. Interoperability between those agencies is better, but not perfect. And until the voice of God says, "This is only a crazy person trying to ram her car into a White House perimeter stanchion and nothing else," I'm fine if the Secret Service triggers contingency plans while it prepares for something much worse.
