I think this is maybe the 5th(?) recent investigation into various police who have been caught in sending racist messages about Meghan, and other vile messages about members of the BRF.
This makes me wonder why in the hell Harry would want these people anywhere near his wife and children if they were to visit the UK
"The Duchess, who has been a frequent target of vitriolic and often racially tinged criticism, is now reportedly facing racist posts from a UK Police WhatsApp group. The information, made public by Sky News, includes despicable racist and misogynistic comments about Markle, Queen Elizabeth II, and other members of the Royal Family.
The report alleges that the messages were shared by an officer whose ex-wife submitted screenshots of the conversations to West Yorkshire Police. Describing the messages as 'racist and vile,' she expressed deep concern over the apparent amusement the officers derived from the misogynistic content. This incident casts a disconcerting shadow on the integrity of those who are duty-bound to serve without bias."
