So why is Harry safe but not Meghan and the kids?

Sorry if this is obvious/already discussed.. I can’t find it.

Im just wondering why Harry can do these ‘engagements’ but his wife and kids can’t step in the country.

It's nothing to do with Meghan and security. She fears being in public in the uk and someone giving her a dollop of hometruth.
