Royal Nazi Salute

Not as much outcry over the Royal Family making Nazi salutes as i imagined, mostly because everyone knew Edward VIII was a Hitler fan anyway and the Queen was only seven and her sister Margaret just three so they can be excused.
What i am not hearing is why the Queen's Mother, the other grown up in the picture, is merrily heiling Hitler and she has no such excuse of being too young to know what she was doing.
Buckingham Palace said it was disappointed that the film had seen the light of day and was investigating into who had released the 20 second movie to the Sun Newspaper, not disappointed that the Royal's had been shown making Nazi salutes.
Very few people seem to be mentioning that there is also a 33 year old woman in the photo, who obviously knew what she was doing.
