On January 16, President Obama asked Congress to approve a $500 million plan with the goal of suppressing gun violence, including measures to limit magazines for military-style assault weapons to 10 rounds, making universal background checks mandatory for gun buyers and adding resource officers to schools that want them. Obama asked for $10 million for the Centers for Disease Control and other agencies to research the causes of gun violence, specifying "research into the effects that violent video games have on young minds."
On January 24, Vice President Joe Biden held a "Fireside Hangout" to field questions about the proposal, noting again that there was no relevant research into the effects of violent video games on human behavior.
"There is no hard data as to whether or not these excessively violent video games in fact cause people to engage in behavior that is antisocial, including using guns," Biden said. He mentioned a study from the American Academy of Pediatrics that concluded that children watching three to six hours of video games can lead to aggressive behavior – the study didn't extrapolate to violent behavior, however.
"So I recommended to the President that we do significant research," Biden said. "Let CDC, let the National Institute of Health, let these people go out and look at the pathology that's behind this, if there is a pathology related to gun violence. We shouldn't be afraid of the facts."
