I have a bunch of letters, some handwritten, sent to the UK Ministry of Health. There appear to be no redactions (unlike the MEPO files documents). There are names and addresses on the letters. One (where I have checked the name online) seems to be from someone who is still/now a scientologist (???) Others are clearly from concerned family members e.g. parents of those who have joined the cult. I'm kind of surprised that these personal details have been left in there... but then the letters are from the 1960s. Should I be concerned about posting?
