This Article explores the evolving law of bystanders in the campus-safety context. In the college or university setting, bystanders include students, professors, and other college or university personnel who hear or see violence in the making, such as verbal and physical harassment or related conflicts that may escalate into assault or battery. Bystanders also include those persons possessing information about individuals in trouble or potentially volatile situations who, by taking appropriate steps, can help avert violence. As demonstrated in numerous media reports of recent college, university, and school violence incidents, there is often substantial evidence before a violent event occurs that could have been used to prevent it. Typically, bystanders with information about a potentially volatile situation do not know what to do. Taking no action runs the risk that violence will occur and individuals will be hurt. Precipitous action on a perceived threat, however, risks stigmatizing college students who might never become violent and are simply acting out.
