There is a causal link between violence in video games and violence in society. If anyone disagrees with this they are kidding themselves and I will gladly accept all flames/attacks in contrast to my statement of fact.
I would suggest that jackson117 read up on such definitive works as
Stop Teaching our Kids to Kill or it's precursor
On Killing by
Lt. Col. David Grossman. You can also read up on such programs as the
CeaseFire program by Dr. Gary ****kin in Chicago for starters.
I studied Col. Grossman's work in recruit training and I'll tell you without hesitation that I didn't believe it at first. But the reality is that we are inadvertantly using
Operant Conditioning to train kids to kill. We are in fact giving them the same training that we get in law enforcement and the military and we don't realize it.
I had the priviledge of meeting Col. Grossman at one of his lectures. It was there that he emphasized, "you can't just MSU. You can't just Make Sh*t Up. The research is in. The facts are there for all to see. There is an increase in violence in society and we can corrolate it to the source."
The AMA in it's
report to Congress stood up with the American Society of Child Psychologists and many other national scientific and research bodies to present the facts but nobody really seemed to listen. More school shootings continue to happen and still the public doesn't listen. Even here in Canada we are feeling the effects of what we've sowed in terms of media violence and still people won't listen. It reminds me of a ostarich putting it's head in the sand sometimes.
If the OP wants more sources to back my claim that there is indeed a link between media and video game violence and societal violence I'd be happy to provide them. To those that have a dissenting opinion I encourage you to provide me the sources that back your claim.
