It's a matter of which way you look down the spyglass. The vast bulk of violent criminals are male, but the vast bulk of males are not violent criminals. So only a small percentage of prisoners go on to commit crimes when released, but they commit many crimes.
As you say, the statistics show that the vast bulk of crimes are committed by repeat offenders. That's why I introduced this table that shows it's a matter of the glass being half full or half empty. I would like you to focus on the costs that victims bear and not just the imprisoned, for whatever reason.
