"Games like Bulletstorm cause violent behavior and, since rape is a violent crime ... ergo, there is no question that [violent videogames] cause an increase in rape." - all this without a single report that links violent videogames to criminal violence of any kind.
By the same logic: "I'm eating an apple. Apples are fruit. Bananas are also fruit. Ergo, I am eating a banana. Q.E.D. PEACE OUT, BITCHES."
