That's happened in a LOT of government buildings. It creates a great many problems, and it doesn't offer much real protection. Typically people coming in the front door are treated like potential criminals, but a dozen different kinds of shipments and deliveries are not even checked- sometimes the loading docks are wide open. A typical office building gets a lot of deliveries and uses a LOT of supplies- it's just not practical. All the front-door activity is just to make people think something is being done. It's easier to make people jump through hoops (almost literally) than to really secure the area.<br><br>I suppose, when terrorists start using high-tech plastic or ceramic weapons, or just sharpened dowels, they'll want to start pulling our teeth in reaction. If they ever use unarmed martial arts, we may have to start amputating. <br><br>The principle is just wrong- disarming decent people makes the situation worse, not better. The goal seems to be to make sure that, at whatever level, the terrorists or criminals will still be better armed than their victims. You'd think more would have picked up on that after flight 93, but I guess we're going to have learn a still harder way.<br>
