Fecal, you need to understand what causes a child to develop into a murderer. You can thank TV, Movies, Video Games, not guns.
From Lt. Col. Dave Grossman:
The training methods the military uses are brutalization, classical conditioning, operant conditioning, and role modeling. Let us explain these and then observe how the media does the same thing to our children, but without the safeguards.
Brutalization, or “values inculcation,” is what happens at boot camp. Your head is shaved, you are herded together naked, and dressed alike, losing all vestiges of individuality. You are trained relentlessly in a total immersion environment. In the end you embrace violence and discipline and accept it as a normal and essential survival skill in your brutal new world.
Something very similar is happening to our children through violence in the media. It begins at the age of 18 months, when a child can begin to understand and mimic what is on television. But up until they're six or seven years old they are developmentally, psychologically, physically unable to discern the difference between fantasy and reality. Thus, when a young child sees somebody on TV being shot, stabbed, raped, brutalized, degraded, or murdered, to them it is real, and some of them embrace violence and accept it as a normal and essential survival skill in a brutal new world. (Grossman & DeGaetano, 1999).
On June 10th, 1992, the Journal of the American Medical Association (JAMA) published a definitive study on the impact of TV violence. In nations, regions, or cities where television appears there is an immediate explosion of violence on the playground, and within 15 years there is a doubling of the murder rate. Why 15 years? That's how long it takes for a brutalized toddler to reach the “prime crime” years. That's how long it takes before you begin to reap what you sow when you traumatize and desensitize children. (Centerwall, 1992).
The JAMA concluded that, “the introduction of television in the 1950’s caused a subsequent doubling of the homicide rate, i.e., long-term childhood exposure to television is a causal factor behind approximately one half of the homicides committed in the United States, or approximately 10,000 homicides annually.” The study went on to state that “...if, hypothetically, television technology had never been developed, there would today be 10,000 fewer homicides each year in the United states, 70,000 fewer rapes, and 700,000 fewer injurious assaults” (Centerwall, 1992).
Today the data linking violence in the media to violence in society is superior to that linking cancer and tobacco. The American Psychological Association (APA), the American Medical Association (AMA), the American Academy of Pediatrics (AAP), the Surgeon General, and the Attorney General have all made definitive statements about this. When I presented a paper to the American Psychiatric Association’s (APA) annual convention in May, 2000 (Grossman, 2000), the statement was made that: “The data is irrefutable. We have reached the point where we need to treat those who try to deny it, like we would treat Holocaust deniers.”
