This is big time stuff. When a person does it twice, wouldn't somebody get it in their head that the first conviction and parole didn't do the job. Human beings are not merely misled. They are not simply astray. They are not innocent victims of a bad environment.
Human beings are intelligent, volitional, choosing, responsible, moral creatures.
People make choices when they could have chosen to do otherwise. That's called moral culpability. Part of that attitude is at the seat of the problem here. We simply don't get it in our court system. And our parole officers don't get it.
