It’s one thing if a violent action like a mass shooting is blamed on video games. It is another thing entirely if acts of violence are directly linked to video games. Unfortunately, this weekend was host to at least two significant accounts of violence and video games.

The first incident came out of Vancouver, Washington regarding Pokemon Go. While there were incidents of violence when the game first came out – even some people luring players into dangerous locations – this new action involved player on player violence. The game has reported few, if any accounts of violence between players despite its somewhat competitive nature.

Friday night, while three men were sitting on a bench and playing Pokemon Go, a man drove up to them carrying a tire iron and shouting, “Which one of you is Andy?” This was after user AndySamberg defeated the assailant’s gym. According to the police report, it is confirmed that the assailant threatened the three men, but the men allege he also punched and wrestled with them.

This incident was followed a day later on Saturday with a much more tragic story. Authorities have released details that late Saturday, two siblings were involved in a dispute over a video game controller which turned violent. Reportedly, the older sister, aged 13, would not give her brother, aged 9, the controller when he wanted to play. The incident ended when he approached his sister and shot her in the back of the head. She was rushed to a hospital where her condition is currently unknown.

These crimes will undoubtedly draw additional attention to the ongoing debate regarding violence in video games and its effect on violent crimes. However, even with the unfortunate and tragic incidents of this weekend, evidence continues to mount that separates these crimes from video games as a primary cause. The head of interpersonal Research Laboratory at Villanova University, Patrick Marky spoke about a recent study which adds to the growing argument against a connection.

However, even the community is divided on such things. In 2015, the American Psychological Association announced that there was a “clear link between violent games and increased aggression,” but reactions even within the association were fairly negative about this statement. One member – who was among 200 other members of the APA to protest the 2015 announcement – went further with his condemnation.

Despite such studies, the video game industry may find itself in a position to be forced to react to tragic stories like the ones that occurred this weekend.
