Kids all over the world play video games, yet only in America is the problem of mass murder epidemic, because of the number and availability of guns. The mental health problems are related to technology, social media and not enough real world social contact, not so much violent games. We also have plenty of American movies and TV shows, we share a living room in that respect and similar demographics, but Canada has a small fraction of the gun murders per capita. We regulate guns and control who can own one and what kind, so do most other free countries, who also have few gun deaths.
