For hundreds of years，the criminal law has been built around the idea that wrongdoers must be punished for their crimes.The most basic argument for punishment is that it preserves law and order and respects for authority.From this point of view，punishment does two things.It upholds the law，and it prevents others from thinking they can get away with doing the same thing without punishment.Punishment is based on the idea that many people have a barely controlled desire to act in forbidden ways.
One of the best ways to reduce crime is to reform or rehabilitate habitual criminals.The main problem is not the first offender or the petty thief but the repeated offender who commits increasingly serious crimes.According to criminologists，crime would decrease greatly if all such offenders could be turned away from wrongdoing.But U.S.prisons have had little success in rehabilitating inmates.About two-thirds of the people arrested in any year have a previous criminal record.
Rehabilitation of criminals could probably be improved greatly if experts could provide the right kind of program for different types of offenders.Criminals vary widely in the kinds of crimes they commit，their emotional problems，and their social and economic backgrounds.Not all offenders can be helped by the same treatment.Many require the aid of physicians，psychiatrists，or psychologists.Others respond well to educational or vocational training.In the early 1990s，there were about 1，300，000 criminals in U.S.city，county，state，and federal correctional institutions，and about 500，000 more were out on parole.Society spent more than $15 billion to operate prisons and related institutions yearly，but only a small part of this sum went to provide treatment.Nearly all the funds were used to feed and clothe prisoners and to keep them under control.
Since the 1ate 1970s，however，there has been a trend toward punishment rather than rehabilitation of offenders.Prison sentences are longer.Capital punishments have been used more frequently since the U.S.Supreme Court lifted a death penalty ban in 1976.Nevertheless，crime prevention should aim to prevent people from becoming criminals in the first place.Such a goal probably would benefit from reform programs in urban slums.These programs would include improved housing，schools，and recreation programs and increased job opportunities.
There are many other ways to reduce crime.People can be educated or persuaded to take greater precautions against crime.They can be taught，for example，how to protect their homes from burglary.Automobile thefts would drop sharply if drivers removed their keys and locked their cars when leaving them.Better lighting helps discourage purse-snatchings and other robberies on city streets and in parks.Many experts believe that strict gun-licensing laws would greatly reduce crime.
