Guns don't kill people, that might sound crazy but guns don't have a brain to have control so a person has to have the brain to control the gun so whatever the gun does comes back to the person because the gun is just doing what the human tells it to do. Think about this if guns kill people then why don't we just send the guns to war? Why do people go over with the guns? It's because the gun is just an object and the person has control over the gun, the gun is just a object, the gun isn't going to just fire if it's just sitting on a shelf, the person has to come in and pull the trigger to fire the gun. It's all on the person, the person has total control over the weapon.
