Barney Ross had a great life cut short by cancer. His boxing career AND his military career are both legendary. He took enormous pride in America, his Jewish heritage, and his own toughness.
He would run into Dorothy Kilgallen in the Stork Club. The other club of most renown in NYC was El Morocco. The two clubs were frequented by the Kennedys, Hollywood stars, Babe Cushing Paley and Bill Paley (of CBS), writers like Truman Capote, and all manner of the rich and famous.
It was Kilgallen’s business to be a regular club girl since she had a gossip column and for many years broadcast a chatty-about-town show from her own breakfast room.
Per my reading, Ruby was upset that the “Jews would be blamed for JFK’s death”, so this is why he went out and shot Oswald. I don’t know if that is in the Warren report but I have heard that.
And Ross seems to have defended the dignity of the Jews, I have heard Ruby did that in Chicago as well.
Because Ruby saw flyers of the JFK wanted poster in Dallas and then, he saw the name at the bottom, Bernard Weissman. I’ll just post a link to a copy of it.

I’ve read a bit into this, Weissman was said to be a Jewish (John) Bircher with a sort of offshoot organization. Weismann was still alive not that long ago and here is his testimony for the Warren Commission.

I’m sure Weissman had no connections to the JFK assassination but they put that flyer out (with JFK wanted on the front) and it must have really stunned him.
