Everyone knows that people make mistakes. Some people make worse mistakes than others, but we are all human. What is difficult for those who commit crimes is that their past mistakes often continue to affect their lives long after they have served a prison sentence and emerged as rehabilitated individuals. It can cause them all kinds of different problems.
Having a criminal record can make it so that you are ineligible for many good jobs and cannot rent a unit in certain apartment buildings. The only way to make it so that you don’t have to inform people of your criminal convictions is to have them expunged. The process of expunging convictions leaves you with a clean record and a real chance at a new life.
