According to the FBI and other sources, the overall U.S. crime rate is the lowest it’s been in over 20 years. The crime rates in almost every category have gone down every year since 1993. There are many theories that attempt to explain this decrease. Do a little research on the web and find ONE theory that explains this trend – there are MANY. Write a word discussion post that briefly summarizes the theory. Try to describe the evidence/data that supports the theory (if any), and offer at least one critique/criticism of the theory (your own or from a source).
