How do you know how Prince Harry will respond in a combat situation? He may be up to the challenge.
We were never taught that Britain entered World War II to protect "freedom of expression", certainly not extending down to the right to wear what you like to a fancy dress party.
It is sad that the tabloid press can find nothing more newsworthy than this story; however, it doesn't detract from the fact that only a simpleton would wear such a costume and not expect to find themselves criticised, particularly if they already have a history of run-ins with the press.
I say that Harry is a twit and demanding a war or threatening that he'd quit without one is poof of his twitery.
