Mexico has one gun store and gun violence is reaching an epidemic
Contrast that to Switzerland were everyone is required to own a gun and it has the lowest gun related homicide rate in the world.
Contrast Mexico to America, where America has 330,000,000 people and more than 300,000,000 guns and we have a lower gun related homicide death than Mexico per capita.
So I would like to know how banning guns solves the problem of gun violence.
