In 2004 a US teenager murdered a homeless man. The teenager blamed his actions on his having played violent video games.
Penny Arcade is a blog comic about video games. Gabe, one of its authors wrote a response to the story that ironically(?) blamed the kid’s parents. Gabe then received an extraordinary letter from a reader who claimed to be the murderer’s step-mother. Read all of it. If it’s for real then it tells a tale almost as disturbing as that of the murder.
