Is it really that hard for you to understand?
A gun fires...person gets hit...they are a gunshot victim.
I met a guy who leaned a gun on the side of his truck. This gun slipped & on the way down a twig got caught in the trigger...the guy got shot...if he's not a gunshot victim, what is he?...besides a dumbass.
The man in your example is a victim because he didn't have it coming, i.e., it wasn't in any sense
justice for him to die. Those shot
deservedly, on the other hand,
aren't correctly termed victims.
