Not to continue an off-topic discussion, but the flip side of that is that people, especially the subcultures from which the violence arises, are frequently willing to blame pop culture for violence because they know it’s a distraction. This goes all the way back to moral panics of the mid-20th century, and probably back to the dawn of recorded time before Socrates was executed for challenging the status quo. This isn’t to compare Millar, GTA or Kingsmen to Socrates - being familiar only with Socrates, I still feel safe assuming none of those other three are as valuable - but just to point out that the criminals love it when they can focus the ire their choices provoke on a handy scapegoat, be it pop culture, mental illness or anything other than their own responsibility.
Hate groups like Trumpistan will always find something to scapegoat, even if it’s something as otherwise innocuous as Pepe the Frog. Politicians and pundits especially will decry violent video games because the NRA, not EA, are funding their campaigns and slush funds.
