In early July thousands of mourners took to the streets in Egypt, chanting “Down with Germany.” Thousands more Arabs and Muslims joined them in protests in Berlin. In Iran, President Mahmoud Ahmadinejad added to the outcry by denouncing German “brutality.” The provocation was the murder on July 1 of Marwa al-Sherbini, a pregnant Egyptian pharmacist here. She was stabbed 18 times in a Dresden courtroom, in front of her 3-year-old son, judges and other witnesses, reportedly by the man appealing a fine for having insulted Ms. Sherbini in a park. Identified by German authorities only as a 28-year-old Russian-born German named Alex W., he had called Ms. Sherbini an Islamist, a terrorist and a slut when she asked him to make room for her son on the playground swings. Ms. Sherbini wore a head scarf. The killer also stabbed Elwi Okaz, Ms. Sherbini’s husband and a genetic research scientist, who was critically wounded as he tried to defend her. The police, arriving late on the scene, mistook him for the attacker and shot him in the leg. More than a week passed before the German government, responding to rising anger across the Arab world, expressed words of sorrow while stressing that the attack did occur during the prosecution of a racist and that the accused man was originally from Russia. Dresden is one of the great cultural capitals of Europe. It is also the capital of Saxony, a former part of East Germany that, along with having a reputation as Silicon Saxony, has made more than a few headlines in recent years for incidents of xenophobia and right-wing extremism. One wonders how to reconcile the heights of the city’s culture with the gutter of these events. MICHAEL KIMMELMAN reports.
