Regarding the VA Tech gunman:
"Several Korean youths who knew Cho Seung Hui from his high school days said he was a fan of violent video games, particularly Counterstrike, a hugely popular online game published by Microsoft, in which players join terrorism or counterterrorism groups and try to shoot each other using all types of guns." The Washington Post, April 17
I know video games are not the root cause of the tragic turn to evil that this young guy made, but surely allowed for a certain amount of desensitization to violence.
Can't say much more. It's all too sad. Many prayers for the Tech community and those who have lost loved ones.
