With no evidence the proper assumption would be no assumption. But evidence was presented child sexual abuse declined since 1990. The question was how to explain it. Punishment severity doesn't much reduce child sexual abuse probably. But not because it's a sick compulsion. Punishment severity doesn't much reduce most crimes. Financial crimes included. They mentioned chances of being caught also. Punishment likelihood is an effective deterrent generally. Pornography could be a factor. Many studies found rape decreased in countries when pornography became more available.
