September 16-22 is the Global Week of Action Against Gun Violence; which makes Wednesday’s shooting, in which a 13-year-old accidentally shot his friend with his father’s gun and then shot himself, even more tragic. The gun, which by law should have been stored unloaded in a safe, was left under a mattress. In a similar incident last month, a 6-year old shot and killed her best friend with her grandfather’s gun – which was also not safely locked away.STATEMENT: Children cannot be gun-proofed
