It occurred to me that the WT, if they can identify the activists that are currently campaigning against them, would have a lot of ability to compile detailed dossiers on them. Once identified, the elders of the appropriate congregation could be asked to forward copies of all their membership details held locally.
Would they do that, and do such dossiers exist?
(There are probably data collection rules governing such things in a lot of countries, but by no stretch of the imagination could the WT be considered a good corporate citizen)
