They got away with it because the vast majority of JW's don't read the Bible, their literature or anything else.
They go to meetings and get pounded with cult reasoning/phrases and repeat it over and over over.......dare I say "repetition for emphasis'
It is literally shocking how FEW JW's have ever read anything from the Society.
Proof? Listen to those 'elders' on the stand during the Australian hearings. They are clearly very, very uneducated people....regarding their own damn religion!!!!
