Review on 60 Minutes piece on Videogame-inspired violence
This is a pretty decent segment by segment analysis on videogame's impact real-life crime: Citing a recent "GTA"-inspired murder of a police officer.

Though, I do sympathize with the sentiment of "why-develop-a-game-that-could-glorify-[insert horrific act here]", the seemingly complete abrogation of any parental responsibility for this crime is beyond my comprehension.
