I don’t think Hitler had any explicit program of extermination of his own elderly population. There is no need to make up bad things Hitler did as he did more than enough evil things to burn in hell for eternity.
It is very simple. The police should not have shoved the man like they did and the man should not have been there. The man being in the wrong did not justify in anyway the actions of the police and the actions of the police did not justify in anyway the man being there. The wrongs of one side do not make the wrongs of the other side right.
