Thinning Out The Prisons, Ctd

The Supreme Court ordered California to release tens of thousands of prisoners. Marc M. Howard isn't anticipating a crime wave:

Much of Michael Tonry’s research has discredited the crime-prison argument.  In a piece with David Farrington, the authors show that the U.S. and Canada have had similar trends in crime rates over decades … , yet there is “no resemblance between American and Canadian imprisonment trends.”  The incarceration rates in the U.S. have soared since the mid-1970s, while the Canadian rates have remained level—at about 110-110 prisoners per 100,000 people—over that same time period.  If the crime-prison argument were accurate, the Canadian crime rates should have gone up, rather than remaining at stable or declining levels.
