Knives and restaurants
Think of the last restaurant you went to. Did you have a knife on the table? Did you know that knives can do real harm if they are used to stab people? Have you seen our new restaurant? We keep each customer in his or her own cage, so that no harm under any circumstances can be done to others.
You wouldn't expect that, would you? We have common rules and consequences for stabbing each other in restaurants, and they work.
Why would you expect individual cages in your institution when it comes to using Wikipedia?
