Well, the witnesses are still expected to keep notes about these things. But there is a great difference if they write it down to a slip printed by an organization or to a notebook of their own.
1. If they would use these printed slips, it could be argued that the organisation is directing/demanding/encouraging them to maintain potentially illegal person data record.
2. If they use their own notebooks, they do not keep these records because an organisation asked them to, but because they by themsselves as private persons decided to do so.
In case there would be a question about potential infringement of privacy laws, which case do you think JW as organisation could better defend themselves against?
