While many people in Minneapolis may think that longer and more frequent prison sentences will be an important deterrence to anyone convicted of a crime, they would be wrong. According to the PEW Center on the States, longer prison sentences do little curb non-violent offenders from getting in trouble with the law again. That means sending someone who was convicted of marijuana possession to prison for several years isn’t going to help him or her break a drug habit and he or she may just be back before a judge in a few years’ time.
