fischer took part in some street battles when the anarchist "putzgruppe" attacked the police and hurt some officers a lot. (in german the word "putz" can mean a cleaner, but in "putz-group" it is an acronym. that means the letters stand for other words. "proletarische union für terror und zerstörung", i.e. "the workers union for terror and destruction"). photos of one battle in march 1973 show fischer clubbing policeman rainer marx . getting a workout (photo)
