On Monday, more than a hundred and fifty gravestones were found damaged or toppled at a historic Jewish cemetery near St. Louis. As soon as she heard the news, Karen Aroesty drove to the cemetery. Many people she knew are buried there. Though she has seen numerous instances of vandalism in her seventeen years at the Missouri/Southern Illinois office of the Anti-Defamation League, which she now directs, this one was especially painful. “I was surprised at how I felt,” Aroesty told me on Tuesday. “I’ve been doing this for a long time. The sadness that I felt was startling.” Chesed Shel Emeth Cemetery, built more than a century ago, in the St. Louis suburb of University City, had always given her a feeling of calm.
