A 'pap walk'. So they were what ? threatening to sue themselves? well that was not a good strategy then because after that there were no pap shots. So much for them trying to gain publicity on that front then. ???
As I said, either a pap walk or press intrusion, depending on your interpretation. None of us actually know.
However, if it was a pap walk, that wouldn’t mean they were threatening to sue themselves, would it? It would mean they (or one of them) set something up and then they issued a statement complaining strongly about it and threatening to sue the media.
If that was it, it’s hardly unprecedented. Diana used to do similar. A lot. Notably in her leaking and then vehement denial of her relationship with Hasnat Khan, which apparently made him quite cross.
Who knows what it feels like to be internationally famous royalty? Maybe those incidents occur because it feels somehow justified when you consider yourself under siege? Maybe other reasons.
Maybe this time it wasn’t that at all. None of us know for sure.
