I agree with that book, however I see that the underlying dynamic behind it is profit mongering by the for-profit prison and for-profit bail bonding industries, both of which spend huge parts of their profits on political lobbying that increases their profits. Racism and fundamentalist religion notions about punishment are the tools they use to advance their agenda. Just pointing out that we have racist outcomes in the justice system won't change the dynamic of what is going on. Prisons are profit centers. For some.
