If gun homicide is truly down 49% then why so much controversy over wether or not they should be allowed and what not. This will constantly be an ongoing battle

If gun homicide is truly down 49% then why so much controversy over wether or not they should be allowed and what not. This will constantly be an ongoing battle for years to come over gun control. Why blame the gun for random acts of violence when violence is truly uncontrolable. Before there were guns people still committed horrendous crimes. It's the corrupted mind not the weapon.
