Her Majesty made the decisions about Andrew and Harry so why question her on that score? Her funeral = her rules.
Poor 'life choices' by both took them out of the 'working royals' group so it is quite proper they were not uniformed for the events.
Indeed.
Plus, Harry was happy to further break protocol with the holding hands routine as well while walking behind the coffin, which would have been even worse doing that, had he actually been in uniform...!!
