The modern phenomena of children going into schools and killing other children is a modern, media driven event.
Everyone is well familiar with the copycat aspect of this. The media screams at the top of its lungs every time there is a mass murder in our schools.
The school system then responds with letters to the parents urging them to discuss this with their children.
All this serves to put the idea of rampage killing into the heads of children and into the heads of the mentally deranged.
50 years ago, children going into schools and killing children was unheard of…..it simply DID NOT HAPPEN!
That these killings are driven by media violence and screaming news reports is as clear as the nose on your face.
