Students injured in a December shooting at Brown University sued the institution, arguing negligent security and premises liability enabled the attacker to access a campus auditorium and carry out the shooting. The complaints state that the Barus and Holley engineering building and Tanner Auditorium lacked secured-entry measures requiring individualized authorization. The lawsuits also assert that Brown’s urban, integrated campus design contributed to the accessibility of the relevant spaces, alleging that students and non-students could move through portions of the building without meaningful restriction. Plaintiffs further allege that security warnings raised by a custodian about suspicious behavior were disregarded. Brown has not been described in the reporting as admitting fault, but the litigation increases pressure on campus leaders to demonstrate entry-control systems, surveillance coverage, and threat-reporting procedures that meet evolving expectations. For higher education risk teams, the case is likely to be tracked for how courts evaluate duty-of-care in open-campus environments and how institutions document follow-through on safety concerns.
