Or in the case of, down the road, repeating an offense. The judge sees you had an issue in the past, was good for a while, then repeated, suggesting an event or something has happened or that the individual has lost their motivation to stay reformed. Sentencing to time for the crime but then also being able to assist the individual in finding help to get them back on track. We have the systems in place to do this, we just don’t.
Also, when applying for a loan, being a sex offender shouldn’t matter. When applying for a mortgage across the street from an elementary school, it should.
The only way to have a system like that is to keep records, permanently, but decision making is limited.
