It is true that some criminals commit crimes again after they have been punished. While there are several reasons for this alarming trend, some effective measures can be taken by governments to tackle this problem.
There are two main reasons for re-offenders. Firstly, the prison system can make the situation worse. Criminals put together in prison and they make friends with other offenders. While they are locked up in prison, they do not have much to do there, and they would exchange information about what they have done before they came to the prison or they may plan crimes with other inmates. Secondly, offenders often do not have any other means of earning money. They are poor, uneducated and lacking skills needed to maintain a job. Also, a criminal record makes finding a job difficult as people usually avoid hiring ex-convict.
