Democrat Vice President Biden's Study demanded by Democrat President Obama agrees,

“This isn’t just about guns, It’s about the coarsing of our culture.  Yes, that’s what I said, the coarsening of our culture, whether it’s with video games or movies or behavior.  It’s about the ability to access mental health services and the safety of our schools. It’s a very complex problem, and it requires a complex solution. W e need studies – and this is where the entertainment industry doesn’t like me at all – we need studies on what are the impacts on young minds of witnessing repetitive violent acts, either in movies, or on television or in video games. That’s not an indictment of the industry - it’s a recognition we have no extensive modern studies on these things,  I believe we can turn this all around,  

It’s not all because of guns.  

It’s a lot of other things,...But maybe what happened in Newtown is a call to action about more than just gun violence; about civility in our society."
