Customs, traditions, moral values and rules of etiquette, not laws and government regulations, are what make for a civilized society. These behavioral norms -- transmitted by example, word of mouth and religious teachings -- represent a body of wisdom distilled through ages of experience, trial and error, and looking at what works. The importance of customs, traditions and moral values as a means of regulating behavior is that people behave themselves even if nobody's watching. Police and laws can never replace these restraints on personal conduct so as to produce a civilized society. At best, the police and criminal justice system are the last desperate line of defense for a civilized society. The more uncivilized we become the more laws that are needed to regulate behavior.
Many customs, traditions and moral values have been discarded without an appreciation for the role they played in creating a civilized society, and now we're paying the price. What's worse is that instead of a return to what worked, people want to replace what worked with what sounds good, such as zero-tolerance policies in which bringing a water pistol, drawing a picture of a pistol, or pointing a finger and shouting "bang-bang" produces a school suspension or arrest. Seeing as we've decided that we should rely on gun laws to control behavior, what should be done to regulate clubs and hammers? After all, FBI crime statistics show that more people are murdered by clubs and hammers than rifles and shotguns.
