F5 was turning away when the trailing runner decided to cheap shot him. He wasn't fighting anyone - he was yelling. There was an umpire between the players - the situation was done. The trailing runner decided to escalate the situation.He wasn't playing the white knight, he was being a bigger dumbass than F5 had been.
Let's try again. Where did I say that BR's actions were justified?
Also, if there's an umpire between players, that's a pretty big sign that the situation isn't done.
