Quote from Joystiq.com:
Note for future lawyers: "The games made me do it" defense isn't going to work. Patrick Morris, 19, was found guilty in the 2006 shotgun murder death of a 15-year-old boy and sentenced to life in prison.
Morris' mother, Irma Espitia, said she tried to connect with her son but, "He would just go into his room and play those video games." Morris' attorney defended his client with the video game defense, also adding a history of emotional and behavioral disorders -- oh, and use of mind-altering Mario mushrooms. Prosecutors said the drugs and emotional disorders were probably a greater influence on Morris' disturbing behavior and decision to murder than the video games.
Good call.
