Human logic is very simple; If you agree with it, it’s logical. If you don’t, it’s not. Facts just muddle the issue.
Sorry but I find this to be reductive to the point of absurdity. No one who is mentally healthy decided to kill because of the entertainment they were exposed to. Advertisements are designed to stimulate our pre-existing impulses; if you have an innate desire to kill it’s not a movie or video game that is the problem.
I make my living making films and I have thought long and hard about this. I do believe there are lines that should not be crossed in popular entertainment and that there are responsibilities inherent in the act of creating popular art. However absent any data establishing a correlation between the consumption of violent culture and murderous acts I cannot advocate any outside controls on the content of what we create. It’s antithetical to the very notions of freedom this country was founded upon.
The pursuit of artists in this matter is merely a strawman that will detract from the real problems we are facing. We need saner gun laws that close the gun show loophole and create personal accountability for the owners of every single weapon out there. We need vastly increased mental health resources that are readily available to those in need. We don’t need censorship of our arts.
