After the shocking violence of the Sandy Hook massacre, a lot of political debate in the U.S. has focused on the implications of what happened, along with debates about existing gun laws and the potential causes of such violent behaviour. It's a complex issue with arguments about gun control and mental health particularly prominent, though as we've reported previously some inevitably decided to point the finger of blame at violent video games.

After an initial flurry of attention on the issue the debate has largely focused on gun control, but former independent Presidential candidate Ralph Nader has not only redirected attention back at media, but used some fairly outrageous language in the process. He said this to Politico prior to President Obama's inauguration speech.

We are in the peak of [violence in entertainment]. Television program violence? Unbelievable. Video game violence? Unprecedented.

I’m not saying he wants to censor this, I think he should sensitize people that they should protect their children family by family from these kinds of electronic child molesters.

The conclusion is an undeniably strong attack, with Politico suggesting this was targeted at the creators of violent media such as video games. It's another assault on video games and follows industry leaders being called to discuss gun violence, recently, with Vice-President Joe Biden. Why post these comments? Because M-rated and violent video games are being linked, in constructive and occasionally provocative ways, to real-life violence.

The question is, should they be?
