A protestor wearing a t-shirt with a picture of a victim (L) killed by the neo-Nazi group National Socialist Underground (NSU) takes part in a protest in front of the Reichstags building in Berlin May 6, 2013. The surviving member of a German neo-Nazi cell went on trial on Monday for a series of racist murders that scandalised Germany and exposed authorities' inability or reluctance to recognise right-wing hate crime. Words on t-shirt (R) reads, "NSU series of murders: pending questions. NSU - support network: How many are paid by the intelligence service".
