While I thought the Phil Donohue show had an episode I can't find the specifics, but I did find an episode of Geraldo Rivera show from Oct 1988 that was on "Exposing Satan's Underground". I have not gone back and watched it so I don't know the details. I found the general listing on IMDB.comCan you remember any specific shows with those panels, and which mainstream news programs might have hosted them other than the famous 60 Minutes episode?
Perhaps we're having a bit of a semantic issue here. There are (depending on how you count) around 15,000 - 18,000 state and local law enforcement agencies in the US. Whether fraudulent trainers on nonexistent "satanic crime waves" are mainstream kind of depends on how common they are, and perhaps whether their teachings were ever incorporated into larger national or regional training kinds or materials, no?
You can have a little cottage industry of these charlatans bilking money out of Bible belt departments run by misguided Evangelicals without it ever becoming a common thing for most departments or agencies.
