There is no doubt that all sentences for sexual offenses are very much too severe and vindictive. Even Dick's sentence is likely too extreme. Punishment should fit the crime. If the guy doesn't do serious injury, probably a year or two is plenty. The point is that now the punishment fits the person.
Insiders get special leniency.
The rest of us get creamed. The moral is that if you want to molest little girls, first get a job as a prison guard. SCI-Camp Hill has an opening and you'll find lots of criminals already employed there.
