Joe Publius alerts us to a story that I had to check multiple times to make sure wasn't satire. Apparently the British Red Cross got upset that nurse the costume used in a small theater production of a pantomime of Robin Hood (don't ask) included the standard red cross on the hat and the tunic as seen below:
According to the Red Cross, this was an unauthorized use of the Red Cross emblem, which represented a violation of the Geneva Conventions
"We have no desire to be the villains of the pantomime or to appear heavy handed, but we do have a very serious obligation to protect the Red Cross emblem.
"The emblem is a special sign of neutrality and protection recognised by all sides during armed conflicts.
"Misuse of that emblem - even when done in an innocent and light-hearted manner - has to be addressed. Repeated and widespread misuse of the Red Cross emblem could dilute its neutrality and its ability to protect."
I don't buy that at all. It's not like someone was going to get confused by this use in a pantomime production of Robin Hood. The idea that this dilutes the legitimate symbol seems like a huge stretch. Either way, the production swapped the red cross out for green crosses, as if that really makes any difference.
