That is either a lie or the writer doesn't understand the meaning of 100 percent correlation. If it were, then everyone who ever watched pornography would have molested a child. It would be a perfect predictor, and it is not.
Liberty, what law enforcement officials say — for example, the Ottawa County Sheriff in the Holland Sentinel (here in Michigan) and most recently, a prosecutor with the U.S. Dept of Justice in a mtg of pro-family activists in D.C. — is that in every case of child sexual abuse they prosecute, the offender was in possession of either adult or child porn.
Every case = 100 percent.
Now I’m giving you the benefit of the doubt that you simply overlooked the reverse correlation, with enough generosity not to call you a liar just because you did.
