He actually thought that viewing hard-core child pornography--vicariously enjoying the pleasure of torturing children--would keep him from becoming a full-blown paedophile. Meanwhile, he was teaching the importance of meeting the spiritual needs of children through his books and lectures.
What are the signs of a mind so twisted? Very few of these professors were found out because they were actually caught molesting a child, but many of them had been doing so for years--one man even adopted a baby specifically for the purpose of being able to molest him with regularity. What they all had in common was that they started out by watching porn--due to the capabilities of today's internet technicians, that's as far as some of them got before getting caught. Others were actually in the business of producing hardcore child porn before it finally found them out.
The government officials who investigate these crimes face two major threats: one, that they may end up losing their jobs when they catch someone so high up the chain of command that no one will dare to prosecute him. We're talking someone above the level of a college president, because there's one of them on the list. Someone so highly placed that anyone who tries to bring him down will at the very least lose his job; more likely his life.
Secondly, they face the risk of becoming drawn into the very pit from which they are endeavoring to pull others. No doubt several of these professors were first exposed to abusive pornography through their studies--Alfred Kenzie certainly felt the need to dabble in it to develop his celebrated human sexuality curriculum at Indiana University. He was under investigation for trafficking in paedophilia at the time of his death in 1956.
Well, child pornography, at least as practiced by those lower on the ladder, enjoys no legal protection in Donald E. Ratcliff's county, state, and country. Wheaton College summarily dismissed him; Brenda, his wife and co-author of his final book on the spirituality of children, divorced him and married a Californian; their three children, whom the book's introduction credits with "overlook[ing] our failures" in parenting, disowned him; and even though he escaped having to go to prison, he will be haunted for the rest of his life by the label of sexual predator, with its onerous attendant restrictions. What he claimed at the time to be harmless-even therapeutic--has ruined his life. But how many more like him are still out there, waiting for an investigator to take the time to find them out?
