Same as Blues Brother - nothing I saw in JCs raised any flags whatsoever.
The JCs I was involved in were the usual run of the mill - adultery cases, courting couples having pre-marital sex , smokers ( cigarettes , pot ) , boozers etc. Often repeat cases and most involving marginal JWs that basically believed but couldn't live up to the rules. Generally just private / public reproof - I think only two or three got DFd and they were pretty much open and shut cases. Apostasy cases were rather rare back then pre-internet - I never dealt with one.
