@User14March I mean interpreting Harry's understanding of legal findings is always tricky! We know RAVEC use a 'case by case' approach to his security so I guess soemone has tried to use illustrative examples that he is twisting/failed to understand.
If he is invited to family or State occassion - he will have full security either down to nature of event (funeral/coronation etc) or her will have full security because he will be covered by King's security/in royal palaces etc
Other attendances - whether visting friends or charitable endeavours - security assessment will determine security need.
He has to give notice for such attendances to allow time for assesment and deployment of assets - although emergencies will be accommodated (as illustrted when he cae over after KC's diagnosis (although that would be covered by family cover anyway...)
