The dead man shoved this guy so hard that he fell down. Then the dead man stepped forward.
Ever seen what people to those who are lying on the ground?
Drejka pulled his gun, the dead man stepped back, and then Drejka fired.
The whole thing is a clusterf*ck on every level, but it's clear that Drejka didn't carry a pistol in order to shoot people for "whatever small reason."
He was assaulted with great force. Only then did he pull his pistol.
You are deeply dishonest.
