É isso aí, rigor na justiça e conservadorismo social é o que fazem com que o crime diminua:
I tend to be skeptical of mono-causal explanations when it comes to social phenomena and behavioral trends. These tend to be the result of a complex, and sometimes mysterious, interplay of events. For examples, since the early-to-mid-1990s, out-of-wedlock births have increased from less than 30 percent of all births to more than 40 percent of all births today. Yet during that period almost every other social indicator — including crime, drug use, welfare, education test scores, teen suicides, divorce, and abortion –improved. In some areas, like crime and welfare, the progress has the dimensions of a sea change. This is a remarkable, unexpected and encouraging development. It also reaffirms the conservative belief that modesty and caveats are in order when it comes to our ability to understand, let alone predict, social trends and human behavior.
