I will shoot the person who gives me a gun. Guns aren't about self-defense, but defense system of an ideology, a country, a religion. The design philosophy of a gun is that its more effective if you make someone else use it while you cower in your bunker. In personal use it offers no protection, it only functions if you shoot first. That marks you as a threat that has to be shot first. Guns aren't about self-defense.
Bombs on the other hand. Touch me and we all die.
