Bennett's argument is based on the assumption that people are safer when there are fewer gun restrictions, but there is little evidence to suggest this. While the campus-carry debate is relatively recent, what research has been done around the subject suggests the opposite. "Many states relaxed restrictions on concealed and open carrying of firearms based on claims that such policies reduced violent crime," according to a 2016 report by Johns Hopkins University . "But the best available evaluations of these policies indicate that these right-to-carry laws increase violence."
