There are lots of hand guns and rifles in USA, right? Is it not a threat when one's neighbour (maybe even of different ethnic origin or religion) buys one and brings it home... should he not be shot at latest at that moment... rather already when he says he is going to buy one??? 
Good example. Let's imagine........
You are living in the little village near the wood. Every night wolfes are coming into village and stealing stock.
Your neighbor purchasing a gun for selfdefense. At this moment, is he dangerouse for you? Looks like no. Because he is defending his property. And you hope, that he will help you, if wolfes will attack your own farm.
And now let's look from wolfes position.... Who is more dangerouse? Sure, a man with a gun. Because he will kill you when you'll attack HIS PROPERTY.
Now I'll ask.
Why you are so afraid of the gun? May be just because of you are on the side of wolfes?
