Here are the photos. The one on the left is from my school book printed in 2010 and the one on the right is from my uncle's from 1982. I think the one from my uncle's book is the original, but how, why and by whom was the photo edited?
Hi. The picture is showing Michael Siegel a Jewish lawyer/attorney from Munich and was taken in March 1933. Mr. Siegel was working for a client who has been transported to Dachau. When he went to the police headquarters to inquiry about that he was beaten up by SA men and then they paraded him through the city. On the original negative the writing on the sign is not readable, both of these fotos are edited. What it actually said is not 100% clear, but most sources claim it was actually the left one that is more accurate ('Ich werde mich nje wieder bei der Polizei beschweren')
Cheers
