You mean an Arab was working as a waiter at the wedding of a Jewish couple and guests at the wedding confronted the waiter because he was an Arab? That sounds like bad guests if that is the story but hardly worth a police attack. If this was people not part of the wedding who invaded the wedding to start up with an Arab waiter who had done nothing wrong then I would not mind the cops taking them out if they were in effect disrupting the wedding.

The guests at this Jewish wedding did not want to be served by an Arab Nazi waiter. In my opinion, that makes them excellent guests. It is an abomination to employ and assist the murderous enemies of the Jewish people.
So the police came charging into the wedding with batons and tear gas because the Arab Nazi waiter was offended. The police disrupted the Jewish wedding, beat and injured Jewish guests, and then had the chutzpah to arrest the Jews whom they had beaten and gassed. In other words, the corrupt police acted like stormtroopers.
If the police in the United States or Europe had behaved like this, everyone would be filing lawsuits and complaining and there would be a grand jury convened to indict the police who abused their power in such a grotesque fashion. But in Bolshevik Israel, police anti-Semitism is considered acceptable.
