Sorry Phyllis, it's not the violent games that are causing the murders; it's pathetically poor parenting.
Your so-called study on game violence is a piece of biased, discriminatroy, totally unscientific trash. The fact is, sales of games with violent content have exploded over the past decade. Gun sales have similarly skyrocketed. But the gun murder rate has steadily decreased that whole time.
Your whole argument today has more holes in it than a spagetti colander.
