Two developments underscore rising tensions between campus communities and federal enforcement. A 21-year-old college student in Southern California says he was blinded by a projectile fired by federal officers at a protest, highlighting physical risks for student demonstrators and raising questions about university responsibilities for protest safety. Separately, a federal judge in Minnesota barred immigration officers from detaining or using tear gas on peaceful protesters, a ruling that affects how campuses and law enforcement manage demonstrations. Together the stories matter to campus safety directors, legal counsel and student-affairs staff managing First Amendment events and federal agency activity near universities.
