For the common, prisons are the places where notorious criminals are kept and if they are allowed to go outside, will commit another crime and reach the prison once more. This is because people do not get chance to know more about prisons and its aim. The wrong ideas about prisons are created by films, periodicals, and other mediums of communication. Most of citizens, who are faithful to law and order in their life, do not get a chance to visit a prison. Moreover, people do not like prisons because it is considered as the place for punishment and imprisonment. But modern concept of criminal sentencing laws is closely related to the rehabilitation of the prisoner who is sentenced for the crime that he/she had committed. It was because of the change in attitude towards prisoners in 1980s and 1990s. Hence, there was a combination of theories like deterrence, rehabilitation, incapacitation and retribution. One can see that the aim of deterrence is to prevent the criminal from further crimes, rehabilitation is to help the criminal to be a part of the society, incapacitation is only a typical reason for the imprisonment, and the aim of retribution is to punish the criminal under proper law. These measures are aimed to reform the future of sentencing but now it is in the hands of permanent sentencing commissions. Ronald F. Wright points out that: “In virtually every case, the legislature has created a commission to direct future adjustments in sentencing laws. (2) The United States Sentencing Commission is the most visible of these administrative agencies.” (Wright, 1994). In US, there are commissions to direct the future adjustments in sentencing laws. Moreover, The United States Sentencing Commission can be considered as the most important of these administrative agencies which are aimed to create humanitarian out look to sentencing laws. So, it is evident that innovations in the field of sentencing laws are aimed to rehabilitate the person who is under suspicion of crime. The aim of criminal sentencing must be rehabilitation of the person who is under suspicion. The best way to punish a criminal is to make him/her convinced that, punishment is for the crime committed not for him. Imprisonment or locking up is a new idea and the punishment for crime in older days was so severe. If the punishment is able to transform the criminal’s mind, the aim of punishment is fulfilled. But when a young man/woman is sentenced for life time imprisonment, there is high chance to acquire the criminal tendencies of fellow prisoners. Community service is the best way to transform a criminal to a faithful citizen. When a person is kept away from society for a long time there is less chance for socialization. As man is a social being, proper socialization is important for individual development. The best punishment that can be given to a criminal is community service, not lifetime imprisonment. Punishment must be able to transform a criminal to normal level. Community service can be considered as the best way to attain the aim of punishment. But when people who committed less offensive crimes are imprisoned for a long time, there is high chance to have contact with criminals in jail. But, this may affect the real aim of punish
