A gun can't shoot someone without the trigger being pulled. A knife can't cut people without something moving it in motion. A car can't hit someone without a person to drive it. Planes can't crash into buildings without someone flying it. My point is, nothing is a deadly object until it is used as one. If you want a safe world for your family. Eliminate the human element.
Giving up guns just alters the method in witch they kill you.
Have a gun, have a chance.
