Partner support

[Rob1968]

I spent some time observing a big youth tourney last week, and doing some mentoring/evaluating. One circumstance seems worthy of discussion here:
Late in a HSBV game, leading coach questions one of the officials on a no-call/possible dbl dribble, which the official admitted he didn't have a great look. But, his comment to the coach didn't satisfy the coach, who continued to follow him from his bench area to the front of the scorer's table. The official finally, and without being overly stern, gave him the stop sign, and said, "Coach, that's enough. We're going to play ball."
The coach turned, to go towards his bench, and then said to the other official, "Well, can I talk to you?" That official was well aware of his partner's conversation, but chose to engage the coach for several sentences, regarding the same play.
It was obviously a "divide and conquer" attitude by the coach.
I talked to both officials after the game and told them that in that situation, the stop sign should be taken as coming from the crew, and the second official might better have avoided that conversation.
Thoughts?
