Are violent video games, TV, movies having a negative impact on youth?

Gun control seems to be the dominant topic following the Sandy Hook tragedy, followed by mental health.

But there are some people who are also concerned about the violence in movies and video games.

They question whether those forms of entertainment may be a factor in all these shooting tragedies we hear about.

There's actually one senator who wants experts to take a closer look to see if these violent game and movies are playing a role.

Senate Commerce Committee Chairman Jay Rockefeller introduced a bill this week, according to Politico .

Under the bill, the National Academy of Sciences would explore whether violent games, especially interactive ones, are having a negative impact on our youth.     

There have been reports that Adam Lanza, the shooter in the Sandy Hook massacre, constantly played "Call of Duty" and "Starcraft."       

The same would go for violent TV content or movies.

According to Politico, Rockefeller is also calling on the FTC and the FCC to toughen up video game regulations.
