The photo below left, which shows Iranian plain-clothes police beating a protester on the streets of Iran, was published on Monday by The New York Daily News. (Taken by Agence France Press/Getty Images, it was photo No. 30 in the Daily News’ special series of Iran images.) The photo on the right is the famous image from Kent State, taken by John Filo in May of 1970, that shows Mary Ann Vecchio kneeling over the body of slain student protester Jeffrey Miller. Both photos feature a woman screaming about the unnecessary violence she has just witnessed. Miller was shot dead by National Guardsmen who felt agitated by students protesting the United States’ military escalation in South Asia. The beaten Iranian man was one of tens of thousands who protested the announcement that Mahmoud Ahmadinejad has been re-elected president. The 1970 Kent State killings — and the protests that followed — swayed U.S. public opinion against the Vietnam War. It’s images like the one below left that will help sway world opinion against Iran’s rulers, and maintain pressure on them to recount the ballots of an election whose results seem so far-fetched.
