I do not agree with Criminal Education 101. That uncivilized creature that kidnapped those two girls seems well schooled in Criminal Education 101. These freaks are running the criminal justice system.
This is very morbid reasoning, but it's valid. It helps to ensure that rapists actually get caught and tossed in jail, and it protects the lives of rape victims. We get this in exchange for shorter sentences for rapists. This beats the hell out of not catching them at all.
