@hamburgboy,
From spiegel.de. Fair use rationale #8: "Images with iconic status or historical importance: As subjects of commentary." This image, of an old man possibly permanently blinded when his eyes were seriously injured by police water cannon, has become an iconic symbol of heavy-handed police force against popular protest in Germany today. The inclusion of this iconic image adds significantly to the "Debate and opposition" section of the Stuttgart 21 article. It would also naturally be relevant to a separate article about the protests against the Stuttgart 21 project, if that section gets split off. It is likely to become a historically significant image of this moment in German history, in line with images such as this one: File:Kent State massacre.jpg.
