When is it appropriate for a referee to involve security during a match?

The appropriate circumstance for a referee to involve security during a match is when spectators are seriously disrupting gameplay. This disruption can manifest in various forms, such as violent behavior, persistent harassment of players or officials, or other actions that compromise the safety and integrity of the game. Involving security ensures that the event can continue safely and without further incident, allowing the referee to maintain control of the match and protect the participants and the audience.

In contrast, situations where a team is losing or where the crowd is displaying sportsmanship do not typically warrant security involvement, as these scenarios are part of the normal dynamics of sporting events. Similarly, uncertainty about a call does not necessitate security intervention, as referees are trained to address such uncertainties through communication and decision-making rather than relying on security personnel.
