Mass shootings frequently provoke discussion around the adequacy of firearm legislation, and what can be done to prevent future attacks. Previous literature examining the relationship between concealed handgun laws and mass shootings provides contradictory findings on what effect gun laws have. Data was used to create a fixed-effects model to estimate if state level concealed carry laws have an effect on the amount of victims a state incurs in a year. Results indicate that concealed carry laws are not significant when estimating the severity of a mass shooting, and are likely not considered when planning an attack. Findings indicate that mass shooting prevention should not focus on concealed carry laws, and efforts would be better spent on studying what motivates the attacks.
