After a campus shooting at Brown University, a pro-Palestinian student was wrongly identified and subjected to a wave of online harassment; the university and campus-safety experts are now urging measures to protect the targeted student and others. Officials said investigators are working physical evidence and DNA as the search for a suspect extended into a fifth day, with police also seeking a second man who may have crossed paths with the possible shooter. Higher education leaders are watching the episode for two urgent lessons: campus safety protocols must integrate rapid threat assessment and victim protection, and institutions must have rapid-response communications to counter misidentification and online mob harassment. Campus-safety experts recommended immediate steps—transparent but careful public updates, victim privacy protections, and expanded support for students facing harassment—to reduce collateral harm while law enforcement pursues leads.
