So you didn't really read the article, just (at most) skimmed for a couple of sentences that went along with your preconceived notion. Remember, most headlines are written by someone other than the author. The headline writer, in addition to just seeking clicks in general, is trying to get Americans to read it. The writer was more focused on the core issues. They brought in the story of one of the protesters to make the point that if Israeli soldiers are that willing to shoot their allies the Americans in the back, they'll positively enjoy the mass slaughter of Palestinians. I will agree with you that in some ways it's not newsworthy, in the same way school shootings are no longer newsworthy in the US, because it's all too common.
