What I'm doing in providing you these figures is showing that the relationship between crime rates and imprisonments is a difficult act. You need to consider a bunch of other factors. Frankly, I don't know the answer to your question, and I don't know which factors in or outside the system would play into this. But it's more complicated than saying that prisons go up, crime goes down. That is sometimes the case and sometimes not. We need more careful analysis, more nuanced claims.
