I don't think Scobie would have been on the Royal rota, and of course it would not have been deployed at a major event such as the funeral.
The Royal rota is a press pool arrangement, whereby various MSM organisations take in in turns to supply staff so that Royal events which for whatever reason (eg location or size of venue, nature of engagement) mean that it makes more sense to cover by a pool, rather than every organisation sending a team. So typically, in the pool there would be one video camera operative, one stills photographer and one print reporter, whose output is then made generally available.
It is not a special club whose members get preferential treatment/briefings/whatever. That's an untruth that seems to have morphed into a myth that just won't go away, no matter how many times its actual nature is explained.
