Is it a Shot Clock Violation?

[Jeremy Hohn]

Well, I have had this happen in a game to me, and I would have to say that whatever sounds first would have bearing. If you have an inadvertant whistle on a try, there isn't any team control, therefore we would go to the ap arrow. If your whistle sounds after the horn and there wasn't any rim contact then we should kill it anyway to give team "B" a fresh reset especially if they don't get it clean.
