twelveways: Of course they blamed something else. All humans do that. No human wants to feel that it was their own fault. If I had killed someone, I would've blamed the Saw movies, Grand Theft Auto, and the song Piggies by The Beatles(like Charles Manson did), just to deemed physically ill, and get a milder sentence.
I just realized that I play games, watch violent movies and pornography, have experimented with drugs, drink alcohol... Brb, I gotta kill someone.
