if you're taking a point from them. suggesting otherwise is one of the craziest things i've ever heard
imagine winning a fight only to be told at the end "hey i took a point or two from you in that 3rd round". a fighter needs to know where he stands on the scoring, in any combat sport, which means you have to stop the action to tell him you're taking the point
whether or not BJM was right to stop that fight at that time to do it is beside the point
