I believe it's legal to call yourself something like Princess Doodle of Dog, so long as you don't use the title to defraud anyone. I'm sure that if I adopted that name and decided to dress in long silk gowns and tiaras I couldn't be arrested for it, even if I got funny looks in Sainsburys. Isn't the classic stereotypical mad person someone who thinks he is Napoleon?
How did this chap get invitations to places where he could genuinely impersonate an Admiral? Aren't they taken from lists of serving (or retired) officers? I could understand a prosecution if he'd tried to captain a ship or something, and I can also understand people being infuriated by his claiming a rank he doesn't hold, but what harm did he actually do?
I don't think he was invited, he just turned up at services etc and people became more and more suspicious. Those who are part of the proceedings ie reading the List of the Fallen, the Exhortation etc, are part of the official party.
Yes, you could call yourself whatever you liked but that wouldn't be dishonouring the fallen and other veterans who earned their medals.
He didn't impersonate an Able Seaman, did he. Oh no, only a Rear Admiral would do!
He must have an inferiority complex and want to make himself seem braver and more important than he actually is.
Sad.
