This just in from the CBC:
"PUNITIVE PARENTING MAY LEAD TO AGGRESSIVE KIDS: STATSCANChildren raised in homes dominated by punitive parenting styles are more likely to bully, get into fist fights and be mean to others, says a six-year study of 2,000 Canadian children.

Yes, “punitive” parenting might lead to more aggressive kids. But one obvious problem with such a study is determining cause and effect. Those who are imprisoned by the government are more likely to commit crimes than the general population.
It follows, by the logic used here, that sending people to jail causes crime.
