It would be easy for cynics to scoff at this valiant man. They could point out that the Red Cross has nothing to do with the Crusades, that it's merely the Swiss flag with the colours flipped. They could observe that it isn't the shape of a Christian cross, in which the vertical beam, if that's the word, is longer than the horizontal. They could even remark that, upon the arrival of an ambulance, the first thought of a person bleeding to death is unlikely to be revulsion at the logo emblazoned on the vehicle.
