8. A number of changes have occurred in the area of law enforcement over the past decade or so. These changes include: (1) truth in sentencing laws, which mandate that individuals who are sentenced to serve time in prison serve at least 80% of their sentence. (2) increased reliance on neighborhood watch programs (in which people in a neighborhood actively report suspicious activity to the police). And (3) technological advances that have dramatically increased the ability of investigators to link specific individuals to a crime scene, primarily through DNA testing. A. Using the model that determines the cost-effective allocation of resources of resources between certainty and severity of deterrence-related efforts, analyze graphically the effect of technological advances that have dramatically increased the ability of investigators to link specific individuals to a crime scene, primarily through DNA testing, on the cost-effective allocation of resources among deterrence activities, and the maximum achievable level of deterrence. B. Using the model that determines the socially efficient level of deterrence (reduction in crime), analyze graphically the effect of the increased reliance on neighborhood watch programs on the efficient level of deterrence 8.
