This is an article by Lt. Colonel Dave Grossman who runs the Killology Research Group. It is an interesting read based on his perceptions that violent video games and media outlets help to condition kids to kill.

His research is mostly based on the works of S.L.A Marshall who was a solider in WWI and WW2. Dave Grossman's think tank takes it a step further though, with customized researchers in educational psychology, abnormal psychology and military warfare practices.

The question is thus...do you believe that violent and gorn porno video games, movies and other media outlets help to act as "murder simulators" for children and to bring down their psychology barrier for the actual act of killing...or do you believe that this type of thinking is flawed and attempts to pass the buck on the responsibility of one's own action.

Here is the long article.
