Considering 67.8% of murders are committed with firearms[1], it's pretty fair to frame this as an attempt to reduce gun violence. Also, this solution mainly focuses on resolving disputes in a non-lethal way that would have been traditionally resolved through murder, making guns an even more relevant focus due to the high death rate of shooting in comparison to non-firearm assault.
