Why is it a rule that if you shoot someone in a death situation that you will be slain for rdm. You literally not affecting the outcome. For example: If someone falls from a HEIGHT YOU KNOW ( such as jumping from the top of the bookcase in Dolls) will kill them why can't you shoot them. Or if in 67th or in Pool if someone is in the water trap why can't you shoot,kill them. It doesn't change the outcome.
The water trap on 67th Way can be deactivated after it's been activated. How would you prove your side that they were going to die from the fall anyway if you killed or damaged them before they hit the ground? The logs won't show up as, Player A took a jump that would kill them, then Player B shot them, then they died anyway. They show up that someone shot a person and then they fell to their death. Staff cannot choose one side or another because instances of RDM like that do happen, so it is RDM either way.
