Sideline abuse is one thing.
Being threatened with a knife is a different kettle of angry, angry fish.
Or, in the case of Northland rugby referees, angry spectators.
Andrew Johnsen, our sports editor, has reported today on the improvement in behaviour on junior rugby sidelines, but the deterioration of behaviour on senior sidelines.
His story quotes Gavin Benney, a former cop who was employed by the Northland Rugby Union to sort out the behaviour on junior sidelines. Not only does Benney have policing experience, but he is a referee as well. He is not prone to exaggerated, outlandish statements, so if he observes that things are bad, then they must be.
