Consider a state with a fixed prison capacity of 1,000. When a law is passed establishing a minimum term of 10 years, (twice the current average term), the state cuts the number of prisoners in half, cutting the probability of imprison- ment for crime in half. Use a graph like Figure 133 to illustrat
