If you have a problem with the picture itself, then that's your problem, because Chomsky didn't have a problem with the event. If you have a problem with the section being misleading in your opinion, as far as I'm aware of you're the only one who doesn't like it in this section, but you could edit the sections of the article if you wish. Wikipedia is editing-driven, so generally you won't get results by just using the talk page, e.g. in this case one of the right-wing loonies was so excited with this picture that he uploaded it twice without noticing, so your censorship crusade is hopeless on arrival, even if you did have arguments for it. I thought that I address your 'informative value' issue by saying that it's obviously more informative than the close-up picture on his face, unless you operate under some new bizarre meaning for the word informative.
