When Harry has made such a massive stink about how unsafe he and is family is in the UK, I wonder whether any family would want their kids attending any school Harry's kid attend or whether any affluent neighbourhood would want them in their midst.
Of course this assumes KC is not going to be providing them with a house on Royal property but even then that doesn't address whether people would feel comfortable having kids whose father has made them targets of terrorists attending the same schools as their kids.
I could be wrong but I certainly would't want my kids attending same school as the Markle kids, not because the kids have done anything wrong but because of their father. It seems to me that the Markles wouldn't be able to hide which schools their kids would attend in the UK as they can in the US..
