About 150 colleges told U.S. News they allow guns on campus in some capacity. Arguments for allowing guns on campus include that campus carry permissions "will make people feel safer, this might actually serve as a deterrent, that these are constitutional rights," says Cheryl Jonson, an associate professor of criminal justice at Xavier University in Ohio. "However, of the limited amount of research that’s out there, we know that might not always be the case that people will feel safer," she says. Jonson points to a 2021 Kennesaw State University study that looked at the effects of a Georgia law allowing concealed carry on campuses. The policy resulted in more guns on campus and increased fear of crime and conflicts, perceptions of the campus as unsafe and lack of confidence in campus police. The study also found that it did not result in any changes in "violent victimization."
