Accusations of cheating and heated arguments erupted during the Cortina Winter Olympics curling competition, centering on Canada's Marc Kennedy allegedly double-touching stones during matches against Sweden and Switzerland. Kennedy was fined for swearing after Sweden claimed he repeatedly prodded stones with his finger to correct their path, an illegal action. Sweden alleged the footage used to prove the infraction was pre-meditated, suggesting a sting operation against Canada.

World Curling responded by deploying extra officials to monitor for double-touching, a move that also affected Team GB and Switzerland. The governing body later relaxed protocols, allowing teams to request stone monitoring for suspicion, though execution remained inconsistent. This controversy threatens the sport's reputation for trust and respect, prompting calls for video review technology like VAR or Hawk-Eye to ensure fair play.
