Why not get together a secret mission to steal the files? Every kingdom hall could be hit on the same week!
Here's the plan. You get dressed up like a brother or sister and just say you're thinking about coming back. Suspicions about you are immediately dropped. You might even get re-instated that day! You case out the place during a Thursday night meeting. Then you plan your coup for one of the next three days.
Saturday would be the ideal time. Usually there's more than one congregation meeting for service and you'll get lost in the mass of people. If someone questions you (perhaps someone you saw thursday night) just tell them you're attending the bookstudy. If there isn't one, feign stupidity and tell them you'll see them tomorrow and go to your backup plan or abort the mission.
If you're not accosted, find a side door that you can prop open. Tape on the latch or a stick would do the trick. Be obvious when leaving. Now, you can return Saturday night after midnight. Take a large duffle bag, a flashlight, bolt cutters, and at least 12 small lock. Now, when you break the locks, remove all of the contents in the cabinets, and re-lock it with a good lock. That way, when the next brother walks by the cabinets they'll be locked as usual. Nothing suspicious. Some KH may have up to 4 congregations, so you'll need two bags or a partner to help you.
Here's the important part; do not take the files back to your place. Put them at a storage locker in the mall, keep them at a friends house, or rent a small storage facility. This is a major coup de tat! KH's around the world will be up in arms. Do not touch the files until the heat dies down (approx. 6 months).
Afterwards, you can do what you wish with the documents. Publish them on the net, send copies to the local police, extort the Org., ect.
This would shake the Org. to it's foundation! Come on people! I've given you the blueprint! Who's in! Stop waiting for someone else and get pro-active!
The Org. is too slow to get word out to every KH PO. Besides, by the time the brothers at the hall
