if you think about it--if an individual decides to label themselves "jehovah's witness"--in spite of never attending a hall--or assembly---never door knocking or reading any watchtower literature---theres nothing to stop them. sure--the watchtower may announce that ( so n so) is not one of J's w's---so what ?
if i tell all and sundry that i'm a jw --why shouldnt they believe me ? no one going to be following me around telling them i'm not.
so--in the case of ms Williams-------i'm sure the watchtowers lawyers have thought long and hard about refuting her claims.----and kept shtoom.
