Now i’m certainly no lover of the Sun newspaper, but why shoot the messenger? Seems like there is a diversion tactic to take the emphasis away from the perpetrator.

The Queen is said to be ‘livid’ over leaked footage of her being taught how to perform a Nazi salute in 1933 as Buckingham Palace launches an investigation into how the clip ended up in the hands of The Sun.
The palace is considering legal action and has begun an inquiry into whether there was ‘any criminality’ involved in obtaining the 17-second film clip, which belongs in the family’s highly-restricted private archive.
And the Queen herself was said to have been deeply saddened that the clip had emerged, especially because it also showed the Queen Mother joining in, and has demanded that the source of the leak be found.
