I also do not agree that the "reform" we need is simply letting criminals go who commit property crime, or because of the socio/econimic circumstance, or any of the other "liberal" or "left" visions of reform
Today's system is centered around punishment, not protection of society, or reforming people, etc. It is just punishment. The criminal owes a "debt to society". I disagree with this model.
There is a whole host of reforms I would support both to prisons, and to criminal justice over all. However simply refusing to prosecute shoplifting, or other "minor" property crimes is not one I can support.
