Why?

The ball is being dribbled, the horn sounds. Why?

A1 is passing to A2 when the horn sounds. Why?

The ball is loose on the floor and the horn sounds. Why?

A1 has the ball for a throw-in after b1's basjet when the horn sounds. Why?

We never blow a whistle in those situations, yet I've never had anyone turn to me and ask, "What was that horn for?"

So why blow it?
