People should generally not be treated like criminals or slaughter cattle, period. I hope every German judge would intervene forcefully against such practices if given the opportunity, on the grounds of article 1 of the constitution:
[Human dignity – Human rights – Legally binding force of basic rights](1) Human dignity shall be inviolable. To respect and protect it shall be the duty of all state authority.(2) The German people therefore acknowledge inviolable and inalienable human rights as the basis of every community, of peace and of justice in the world.
