Very often I listen to a story about a bad choice someone made in their past and paid the price. They have now changed their life or are back on track making good choices. Except every time they look for that job, the employer likes them until the criminal background check comes back. Then it is "sorry, we do not have a position for you."
The goal of these bills is to stop minor criminal offenses from resulting in roadblocks for someones entire life. If passed, I think the biggest impact would be the proposed bill to reduce the 10 year waiting period to expunge a crime down to six years. Six years is still very long, but it is greatly reduced. The problem with the 10 year rule is that it is 10 years from basically the last thing happening in your case. Say for instance you are found guilty in 2000. You are then sentenced to 5 years in jail. You are released from jail in 2003 for good behavior, but are now on parole. You finish parole in 2005. Now you start the 10 year clock. So that means that something that occurred in 1999 or 2000 cannot be expunged until 2015. It's too long to put your life back together effectively. Yes you can make good choices and likely find some job, but it won't be a job that pays the bills.
