This is how the US does it...

This morning, Sen. Jay Rockefeller introduced legislation in the Senate “to arrange for the National Academy of Sciences to study the impact of violent video games and violent programming on children.” It’s depressing to see lawmakers rushing after diversions in the wake of the massacre at Sandy Hook Elementary in Newtown, Connecticut, when the conversations we ought to be having should be about gun control and mental health treatment, among other structural factors. And it’s even worse when you consider that Rockefeller’s wholly redundant bill has hit the floor of Congress before any gun legislation was introduced.
The video game industry will generate $70 billion in 2012, which is more than double what the gun industry will generate in the same period. Yet you will not find a politician who fears the video game industry like he/she fears the gun industry. Obviously the gun situation is not about money or the industry (the base) but entirely in the sphere of ideology (the superstructure).
