When a person decides to break the law, it’s his or her responsibility to take their own punishment. Thus, sending criminals to jail is an effective and necessary method to penalize offenders. Statistic shows that more than 80 percentage of criminals can’t find a propre job or have problem back to social life after been released from jail term. And the main factor which causes this situation is offenders have lost their connection to outside world during prison. Furthermore, rehabilitation program become a major resource for prisoner to be re-introduced to society. Personally, I believe that jail term and rehabilitation program are both essential and important for law breakers.
