There is no evidence that banning assault weapons will reduce the “incidence of fatal mass shootings,” a study has found.

The study, conducted by Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland, analyzed fatal mass shootings in 45 states between 1984 and 2017 and the association between the rates of those shootings and the presence of various firearm laws.
