There is just no word that fits what American and Canadian authorites announced breaking up today. By law, a person can get 15 years for making the stuff - possession is good for five years. That's good enough for a felony, but folks who molest children have proven they cannot be rehabilitated. Those who make child pornography are even lower on the scale.
What ought to be done is an increase in the penalties. Twenty years for a first offense of possession of child porn - life without parole for the second offense. For makers of child porn - the first offense is a capital one, and the condemned is executed via the old-school GRU method.
