Ozzy. These networks were open in the 70s. IE: NAMBLA ( National association of Man Boy Love) met openly in San Francisco at the public library. A story in the paper and public outcry put it underground.
They catch RANDOM pedos on reality TV everyweek here in the US. Volunteers set-up meets on-line (pretending to be children) with pedos and when the pedo shows up expecting a child they get arrested. But those caught are run of the mill low level dumb pedos.
Even the FBI director , J Edgar Hoover in the US and many in British Gov. Had "unusual tastes" not long ago. A Bethel GOVERNING BODY member and other HQ staff were suspected of Child abuse...why would they lead a charge to end it? I believe it would be unlikely for the sophisticated Pedo groups to be infiltrated other than with a computer virus or key logger. The local JW pedos tend to pick victims that are easy and groom the child victims over a period of time.
There is a Pedo group that use "free day-care" or "activities" (like water skiing, pools, hot-tubs, horses, & alcohol, to provide A FUN place to hang out during the summer) to access children and young teens. These adult "JW"s are attractive, affluent, smooth and "fun". Busy, trusting JW working moms are completely taken in by these "friends" and allow their children to spend long summer vacation days at the Pedo's homes, camping, and on their boats. If these trusting JW moms ever find-out anything they first go to the Elders....and some of these pedos ARE the elders........Anyway the pedos always have at least a week to destroy evidence, lawyer-up, threaten the accusers and parents with DF'ing for slander, and lawsuits for defamation. These struggling JW moms are no match for these guys usually just shut-up and just "go away".
