The truth !

[stanc]

Reading the argument that there is no connection linking violent video games to mass shootings seems to be a hasty assumption to me.

It's not an assumption. From the article:

...only last year the Trump administration convened a School Safety Commission which studied this issue, among many others. I myself testified, and the commission ultimately did not conclude there was sufficient evidence to link games and media to criminal violence.

Long-term studies of youth consistently find that violent games are not a risk factor for youth violence anywhere from one to eight years later. And no less than the U.S. Supreme Court declared in 2011 that scientific studies had failed to link violent games to serious aggression in kids.
