Please, I don’t think video games are causal here, though it gives the story a convenient media angle. 20 years ago this kid would have stabbed his brother over Electronic Football.
40 years ago this kid would have stabbed his brother over Electric Football -- the game played on a metal vibrating field.
Actually, he would have stabbed the one football player who always went in circles ...
Sorry, I disagree. I believe the extreme level of violence and disaffectation in hip hop music, violent video games and popular movies (horror, X or R rated, etc) lead all too easily to this type of thing - an impulse that goes too far.
After all, we know the Army uses video games to desensitize their trainees to shooting and hand-to-hand combat.
