No, the reason it is repeated so often is that the absolute denial of Israeli partisans is so transparently false curiosity is piqued. When people scurry down the Identity Politics rathole and start charging "antisemitism" you know something is there.
America was brutally attacked and these Israelis did not cooperate fully with US law enforcement. That tells you all you need to know there.
Trying to disparage the lady who saw the Israelis smiling is pathetic. She had zero motive to make that up. She had no idea who they were when she called the police. She should be praised for being observant and not afraid to get involved.
But you want us to believe she is not credible and the 5 Israelis who hightailed it out of the country leaving behind a going business are credible.
