There has been violence in movies for as long as I can remember. Good and bad guys were gunning down each other back in the days before movies had sound. In the 80's there was brutal torture and rape and gun violence in everything from RAMBO, and THE TERMINATOR to SCARFACE. I watched all those films and so did MILLIONS of other people. Less than 1/100,000th of 1% of the population commit murders. And of those, how many were inspired by violent tv/film as opposed to greed/jealousy/theft/etc.?
If someone is raised properly, with attentive loving caregivers, and taught right from wrong, even at the most perfunctory level, odds are they don’t grow up to be a killer. And then, sadly, there are people that are born broken- they will always be a danger – there is nothing that can be done to help them – that is a painful truth – hopefully they can be institutionalized, humanely treated and taken from society where they could not harm others. To say school shootings happen solely because of violent tv/film … well, that’s just irresponsible.
