The curling controversy at the Winter Olympics intensified Sunday when British curler Bobby Lammie was penalized for double-touching a stone during their match against Germany. Officials removed the stone after video evidence showed Lammie touching it after release, a violation that has now affected multiple teams at the Games.

This incident follows similar allegations against Canadian curlers from Friday and Saturday, where both the men's and women's teams faced accusations of the same infraction. The controversy prompted World Curling to increase surveillance by assigning two officials to monitor all four matches during each round, though they maintain it's impossible to station umpires at every hog line throughout competition.

The British team won their match 9-4 despite the violation, but the growing scrutiny raises questions about enforcement consistency across teams. Until Sunday, the controversy had been limited to Canadian curlers, who represent one of curling's largest fan bases. The expanded surveillance and multiple violations suggest deeper issues with rule enforcement that could impact medal contention as the tournament progresses.
