Firstly, it was removed while he was living in Canada.
Yes, when he was planning to live there long term and was no longer representing the Crown. Exactly as I said. He'lll have known about this in advance and still chose to live abroad and make himself a burden on Canadian taxpayers until they decided they weren't going to subsidise his lifestyle choices any more.
Secondly, Meghan, Harry & Archie’s threat level was second only to that of the Queen (QE2) according to Neil Basu.
I'm surprised this out of date interview hasn't made an appearance before now. Threat levels change all the time, as this person knows very well.
Also, as has been explained many times, 'threat level' is not the only thing taken into account by RAVEC. Even as a working royal, Harry was much less important than the Queen. As a wannabe Netflix producer, his importance declined much further.
Do you believe British taxpayers should be paying for Harry's security to make money from his titles in California? It sounds as if you do.
