Give the original creator an irony transplant - quick!!

Every now and then, I see a meme on Facebook which seems pretty stupid. This must qualify as one of the most stupid I have seen, unless it was supposed to be ironic, which I doubt. It originally had just the yellow text - I have added the white text in case anyone misses the irony: Sgt Blackman, the 'PoW in his own country', was convicted of shooting a wounded Afghan prisoner in the head. While being filmed. And saying he was breaking the Geneva Convention.
