re: Carjackings in New Orleans are the worst in a decade.

The problem is, the law abiding public will basically always be the guinea pigs for your possible alternatives.

I would also question as to whether all these studies are looking at similarly situated criminals. Or might not the ones who are actually being incarcerated be the ones who tend to have a greater general proclivity to recidivism? Chicken or the egg, so to speak.
