Imo those children are the grandchildren of the King, and no matter what silly games their mother in particular are playing , they deserve to be safe if they visit the country they were born in.
Just to check: You do know that Harry has a special arrangement with RAVEC whereby his and his family's security needs are kept under continual review and provided he cooperate with them, all appropriate security will be provided?
You're aware of this, yes?
Harry would have then had the opportunity to work in protecting endangered animals, something I think he would have been excellent at.
Why would he be 'excellent' at this? What qualifications or aptitude does he have? Has he shown any interest in endangered animals outside of a few activities he did as a royal? I'm not aware of it.
