Person A is nazi and killed someone during a protest. Person B is also nazi Therefore person B potentially killed someone during a protest. Therefore we should arrest all nazis

Person A is a jew and lends money and is rich by "stealing" money from the borrowers via interest Person B is also a jew Therefore person b "stole" money Therefore we should arrest all jews
