It says clearly that the concern is directed toward elders acting in local kingdom halls; not the world headquarters.
Years ago as posted by others (I believe possibly Danny Hazard as well) they got a written directive telling them what to do if police ever sought warrants etc. Others are also posting about a tip that some elders in Napa, California where the court ruling was given have already set to shredding documents locally.
I would point out however that even if they shredded everything there will still be people willing to come out with strong, telling oral testimonies; but the written evidence is vital to rooting out the embedded pedophiles.
Readers, please act. I myself am sending a tip in to CNN now that I have the link and it includes my phone number, silentlamb.org's etc. Let the authorities look into the person's tip, please.
