On the assumption that it really was Jews who murdered the Arab boy, it is an abominable act that deserves to be condemned and severely punished.
Clearly, there are Jewish murderers. If the people arrested are proven guilty, it will not be the first time that Jews have murdered. The difference between the Jews and the Arabs is not that both produce murderers. Rather, it is in the legitimacy and encouragement that the Arab murderers receive from their fellow Arabs and leadership.
That is precisely the difference between a regular city and Sodom.
