I can understand being upset over a loss but she had time enough to gather herself before the ceremony. She showed poor sportsmanship, embarrassed her country and she should be punished, perhaps take her medal away from her.Source
PYEONGCHANG, South Korea — The disappointment showed on their faces and for Canadian defenseman Jocelyne Larocque there was no celebration in winning the silver medal.
After the United States won a thrilling shootout for its first Olympic gold in two decades, the medal ceremony took place. Larocque had the reaction that was most noteworthy — yanking off the silver immediately after it was placed around her neck.
It’s not like Larocque doesn’t have a gold. She was part of Canada’s winning team in 2014.
Sometimes emotions take over in the heat of the moment.
