Re: Conspiracy of Silence
I remember a scholarly book on ritual and cultic abuse that said a full 80% of all abuse cases reported abuse in a religious building (church, etc.) at least one time. I'll try to get a list of my borrowings at the library for the title of the book.
Also, the standard form of security these guys have (courtesy of Mike Warnke) is three rings, or circles: the outer circle is there for observation; the middle circle is there to discourage you from proceeding; the inner circle is there to STOP you.
I am guessing that just by the sheer numbers, if you go to enough different churches in an area, you will sooner or later be in one that is used in this way. What signs or behavior to look for is unknown to me at this time.
