So please, do not pull out the past as proof of the present, it does not satisfy.
Your History Does Not Prove You
Lots of people have gotten away with lots of things for lots of years. I will not take a history lesson as proof that you are a good person. You can only be a good person, if you are a good person. You cannot be a good person because for the last 20 years you were not caught at your bad deeds. You can only be a good person if you truly are a good person.
