If you look at the prison population and at the proportion of people who have been physically abused and sexually abused, who have substance use problems, it seems to be a population with a lot of disadvantages and a lot of strikes against them. It's also not that easy to treat. If you can prevent family abuse, child abuse, sexual abuse—and there are programs aimed at that—through national public health programs preventing abuse, it would be a very significant move.
