Nowadays, prison is the most common solution to protect people from criminals but many individuals believe that education is a better decision. I disagree with this opinion but I believe that education is an essential part of prison system.
The most significant reason why I believe that prison is necessary is that dangerous criminals are kept away from society. It would become a large threat to people if murderers, rapists and terrorists were under house arrest and learnt why the crime they did is bad. Prison also prevents from another crimes because individuals are afraid to be put there. If the punishment would be just a education course, they could decide to commit crime anyway. As a result, replacing prison to education may lead to an increase of crime.
However, education is a principal part of prison system. There are a large number of countries where prison is just a place which separates criminals from others. There is no education system in prison so being there can negatively affect on the criminal so he can leave a prison worse person then he was before. Education must be involved in prison system as it is in many european countries. For instance, scandinavian prisons educate lawbreakers so many of them become different people when they leave it.
In conclusion, I believe that prison is neccesary but if there is no education proccesses that enables to change criminal behaviour it become useless.
