You don't have to be able to use a gun for effective shooting to be able to be safe with it. The opposite is not true, IMO.What's the purpose that you know everything about gun safety, but you don't know how to shoot, or can't shoot well?
If someone wants to learn sword skill, I will ask that person to go into the woods and chop down 1,000 tree branches. IMO, to develop gun skill, you have to shoot at least 1,000 bullets (or even more).
Similarly, I can teach someone how to effectively prevent a hip throw without teaching them how to use one effectively (they only need a rudimentary understanding of what makes them "throwable").
