Israeli art students - scam?

Yep, it was BS.
Some of the facts are right though–there was a New Jersery housewife who called the cops, who then arrested two Israelis on a rooftop. But not because they were “filming and dancing”. They were construction workers who happened to be working on the roof, their “dancing in joy” was actually just pointing at the burning powers, and screaming “oh my God, look at that” in a foreign language

They were arrested for not having valid green cards. After a couple months in jail, they returned to Israel and threatened to sue the NY Police for brutality in prison .
