Youre saying that gun is to kill. Of course you need to kill somebody, who wants to kill you. So its for protection to yourself or to your family.
What about a gun control? I think government releasing a license for anyone to get a gun for themselves. So it's gonna be legal.
In India, we need a license to own a gun. The process is so cumbersome and time taking, that less than 1% of the people who want to own a gun end up getting it. The remaining 99% are at the mercy of the criminals.
