According to a WaPo article entitled "Obama heckled in Israel" (http://www.washingtonpost.com/blogs/post-politics/wp/2013/03/21/obama-heckled-in-israel/?wp_login_redirect=0):
"The man was shouting in Hebrew. According to a White House pool report, he was referencing Jonathan Pollard, an American who pleaded guilty in 1986 to passing top-secret information to Israel."
As reported in today's Jerusalem Post (http://www.jpost.com/Breaking-News/Obama-heckler-His-speech-was-extremist-and-Zionist-307394):
"The Israeli-Arab student who shouted a pro-Palestinian slogan, interrupting US President Barack Obama's speech at the Jerusalem International Convention Center on Thursday, said Friday that he had done so because he found the speech to be 'extremist and Zionist.'
Speaking in an interview with Channel 10, Rabia Eid said that 'Obama talked about a Jewish state, and that is unacceptable to me and to the Arabs of the world.'"
Yup, how much easier it is for WaPo to villify the Israeli right in kneejerk fashion rather than check the facts.
