President Trump, weighing in on the ongoing conversation about gun violence in America, suggested laying the blame partly at the feet of pop culture today, citing violent movies and video games as possible causes of the problem.

“We have to do something about maybe what they’re seeing and how they’re seeing it, and also, video games,” said Trump, speaking during a discussion on school safety at the White House. “I’m hearing more and more people say the level of violence on video games is really shaping young people’s thoughts.”

The president is not the only politician, especially on the Republican side, to bring out this old chestnut following last week’s mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, in which 14 students and three staff members were killed. Within two days of the shooting, Kentucky Gov. Matt Bevin had given multiple interviews in which he pointed to violent video games as a factor in such events.

“There are video games, that yes, are listed for mature audiences, but kids play them and everybody knows it and there’s nothing to prevent the child from playing them, that celebrate the slaughtering of people,” Gov. Bevin said in a radio interview.

Florida shooting survivor on Trump’s comment about video games: “That’s just a really pathetic excuse… I grew up playing video games… first-person shooter games and I would never, ever dream of taking the lives of any of my peers so it’s just pathetic” https://t.co/VfXvVkwQmq pic.twitter.com/rBmbqf6dQS — CNN (@CNN) February 22, 2018

Young people have counteracted this narrative, as they have every time it is stated. The survivors of the Stoneman Douglas shooting have taken to activism, gaining a national profile as they advocate for gun control legislation. Following Trump’s comments today, CNN interviewed a student at the school who did not hold back in his response.

“That’s just a really pathetic excuse on behalf of the president,” said Chris Grady, 19, a senior. “I grew up playing video games — you know, Call of Duty, all those kind of first-person shooter games — and I would never, ever dream of taking the lives of any of my peers. So it’s just, it’s pathetic.”

In addition to calling out violence in movies and video games, Trump said that the Parkland shooting had led his administration to consider taking action on policy measures to directly address access to guns.

“Everybody in this room, I can tell you,” said Trump, referencing the federal, state and local officials present at the meeting, “they’re into doing background checks that they wouldn’t be thinking about maybe two weeks ago.”

The president also said he would “work on getting the age up to 21 instead of 18,” a comment referring to proposals that would raise the minimum age for buying certain types of weapons. In addition, Trump pointed out that he directed the Department of Justice to suggest banning bump stocks earlier this week, and said his administration would be “focusing very strongly on mental health.”

Trump reserved harsher comments for films, saying that the current movie rating system, which is administered by the Motion Picture Association of America, may be insufficient in appropriately characterizing and categorizing on-screen violence.

“You see these movies, they’re so violent, and yet, a kid is able to see the movie if sex isn’t involved,” said Trump. “But killing is involved. And maybe they have to put a rating system for that.”

The MPAA has taken plenty of flak over the years for its rating system. Kirby Dick’s 2006 documentary This Film Is Not Yet Rated pointed out discrepancies between the way the organization handles, for instance, sexual content versus violent content. A 2013 study published in the journal Pediatrics found that gun violence in films rated PG-13 had more than tripled since 1985, the first full year that rating was in effect, and that in 2012, weapons were more prevalent in PG-13 movies than in R-rated films. The authors of another study published in the same journal later in 2013 focused on how often violence appears in movies alongside sex, drugs and alcohol, and said that their findings “raise serious concerns about the effectiveness of the MPAA rating system.”
