I don’t think anyone disputes this…

prohibits the naming, accusing or labelling of another person as being a witch

It also prohibits people from practicing as a witchdoctor or a witchfinder

The second clause nullifies the first clause since you can’t arrest someone for being a witchdoctor if you can’t accuse someone of being a witch.

Also, now I have the song stuck in my head. Ugh.
