The Jewish newspaper, Algemeiner, has an article on the UC Irvine incident. It contains a statement by Eric Fingerhut, the national director of Hillel. The article also alleges that some people chanted, "All white people need to die". There is a link below to the Students Supporting Israel Facebook page.
"According to statements by UCI’s SSI on Facebook, protesters also shouted, “All white people need to die” and chased a female student into an adjacent building. They “were aggressive, blocking exits and not allowing people to leave, as well as forcing people to run and hide in their rooms, fearing for their lives.”
