There's a good chance someone you know has a criminal record. Hundreds of thousands of Minnesotans have a conviction for a crime in their past. In most cases they've paid their fines and served their time. However their criminal record follows them everywhere. It prevents many from getting work or a place to live. Some say after a period a time most criminal records should be sealed, what some call expunged. Others say it's important for employers and others to know as much as possible about someone's past.
