Now you’re just dodging.
You and Grossman these games have a role in causing this violence. When someone points out the problems with that theory, you act as if you are being asked to solve the gang problem. No, you are not being asked to fix all violence everywhere, you are being asked to show evidence that explains why gang violence is occurring in certain places and not others, even though the kids in both places play FPS games.
I’ll keep it to one specific question. Chicago and Houston have about the same population, demographics and income distribution. One had several hundred more gun murders than the other. Were more copies of FPS games sold in one city than the other?
I have no idea!
