Air pistol would just seriously annoy whoever you shot with it,its no more dangerous than a sling-shot....A revolver,well that would make sure the person shot with it would either die or think twice before trying to home invade/car-jack or whatever.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
