I would like that pic IF there weren't the Hitler symbol there!!

Swastika is not really Hitler's symbol. I mean, yes, now this is most associated with his sick ideology, but Hitler "stole" it. It has roots in Ancient India, but also was used in other cultures through ages and was symbole of luck and happiness (so far I know, in Asia countries, it still has such a meaning).
Before II World War it was nothing shocking with using swastika in, for example, advertises and other (look here - sorry that it is not in English, but I rather mean photographies than the Polish description)

Sorry, but I'm going back over this and making an executive decision to reverse the call on this one. While everything Camelia said is technically correct, the use of the swastika on an armband worn by Rin in a pseudo-military outfit is quite clear on it's intent in depiction.
