Kimeo, I don't think my kid would have turned into a school shooter.
I do think that repeatedly shooting something that looks like a human is simply not good for you.
If there is a kid with the potential they could, and obviously have in this case, use these to hone their skills increasing the body count once they act.
IMHO it would be far more effective to take away this training tool than to limit magazine size available for instance.
I'm not sure as much as I dislike these games I would be ready to do that but, if our opponents were anything but bald faced liars and hypocrites they would be all over this angle.
