Well, in the school's defence, lots of 9-year old kids still believe in Santa with his flying reindeer, the Tooth Fairy and that the Easter Bunny lays eggs. So while threatening with a magic ring is laughable to us, to the child who was on the receiving end of the threat he/she might actually believe that magic rings are a thing. Hence that child might believe the threat is real and might have been very scared and traumatised by the ordeal.
Whether suspension was an appropriate response or not is a different matter, and one which needs to full context of the ringbearer's schooling history. But bringing the T word into it was completely out of order.
