When you talk about self-defense, even here in India one is allowed to own a gun if he gets a license. It's not impossible to own a gun here, it is just more regulated. That way not every Tom, Dick and Harry can own a gun.

Criminals can get hands on weapons in one or the other way. But giving every one a gun because they have to defend themselves from some criminals is not a good solution. It's better to work towards a better Law and order system.

And, don't make statements like 'You are wrong'. These are issues our and your forefathers have been trying to solve, there is still no absolute right/wrong yet.
