@AuntieBiotics maybe, but that still doesn't make safe to me if they're as unsafe as they claim to be.
Not a chance in hell I'd consider moving my children to a place they weren't safe (unless forced to ie when war disrupts countries)! If that meant they couldn't have the schooling I wanted them to have then that would be very sad but I'd have to accept it as a consequence.
So either they have found a way to live here safely, in which case there presumably isn't a need for taxpayer funded security, or they've grossly exaggerated the risks, OR they don't care about the risks?
It can't be the latter because they genuinely come across as devoted parents.
It's also a bizarre time to move back to the UK, racism has increased horribly here. Why put meghan through that when she struggled so much before?
If for some reason they need a country other than the States to be their main residence then they're fortunate enough to be able to take their pick.
