There is no law of trespass in Scotland. There has not been for....years and years and years, if ever. This is a little fact I remember learning many years ago, when there was such a law in England (I think), although I can't give you chapter and verse and where to find it. However, I do remember that when I used to hike in Scotland and asked landowners for permission to camp on their property, they were a little puzzled. "You can camp anywhere you like," said one, clearly confused as to why I was even asking. But he was Scottish and the long term law of the land was obviously part of his psyche. Not the case with the sheikh or his employees, maybe.
