Problem with child abuse (especially sexual) is that it has the power to make you go "eww" even more then murder. While I'm happy that we finally live in the times where such acts are talked about, and therefore more easily revealed and stopped, there's an unhealthy aura of fear surrounding it. And fear is a powerful way to control someone.

Not to mention that arresting even a potential child abuser gives more love points to the police then solving any drug or murder related case.
