It also analyzes the impact of people's external behavior. In this section I learned about the Problem Analysis Triangle; which is a criminal triangle that derives from the theories of environmental criminology. I definitely find the Problem Analysis Triangle useful because it helps to think about recurring problems of crime and disorder. “Implementing POP in a police agency, as well as in its local government and community, is conceptually simple, but practically challenging” (Scott and Kirby). As I read “How to Prepare Yourself and Your Agency,” I learned that engaging in long-term problem solving will make you an expert problem solver. Not all agencies are the same, some have strategies to become professionals in solving problems that others don't know about. In this week's videos I also learned from Herman Goldstein, an experienced and exceptional person about how he has changed and contributed a lot in the legal community. Goldstein sees Problem Oriented Policing as an effort to refocus attention on the police department. “By examining problems in detail, the legal environment will become more familiar with how to handle and respond to problems” (Learning Resources Video). Herman made me understand what problem-oriented policing is all about today. Something new I learned is that it takes a strong commitment to following problem-oriented policing strategies.
