Yes, treatment should be always the same - the records stay. Two things though - many thigs that are considered a crime shouldn't be a crime, and second, if the crime is minor or irrelevant, the record won't hurt the person, otherwise it's a proof that it's not as irrelevant as you think. For example in my country, you will get even parking offenses (repeated, but still) written in your record. It hurts nobody because nobody cares.
