Still don’t need police escort. Private security will do. (Maybe guards with SAS background?)
I cant stand Harry and Meghan but private security is not the same. They dont have the same access to information etc.
I do think if they take their kids to the UK they should get stepped up security IF Harry pays for it all. Those kids are a prime target for all kinds of mishaps..and the Brits have great animosity toward those two right now.
