It might be possible if the bullet only went through soft tissue in the first body. In the JFK assassination, one bullet allegedly killed the president and wounded John Connally.
Yes, it is very possible, especially if the gun is close to the first person. If I shoot myself, it will go straight through me and to whatever is behind me.
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.
