The most important aspect in the life of civilians is safety. Each day, you must feel safe in your home, and you must feel safe in every aspect of your life in order to maintain a sense of mental stability. The one thing that was emphasized as missing in both "Red Harvest" and "The Death and Life of Great American Cities" was indeed the lack of safety. On the one hand, creating a city without enforced regulations that improve safety is a serious offense. Whereas having a city that does is not portrayed to be safe, is another. Safety is an important aspect of a well functioning city, whether theoretical or real.
