I found a hilarious news at ICv2 which is occasionally quoted by "Eigode! Anime/Manga". http://www.icv2.com/articles/home/9540.html
Lawyer Tries 'D&D Defense'
While the media has occasionally scapegoated adventure gaming(see "Monterey News Story Ties RPGs to Assault") and small time Savonarolas like Jack Chick and "Dr." Thomas Radecki regularly castigate Dungeons & Dragons as dangerous and satanic (see "Jack Chick Takes on Games Again"),
the lawyer for a Detroit man accused of slashing a co-worker to death with a homemade samurai sword may be the first barrister to come up with a "D&D defense," claiming his client was a psychotic schizophrenic obsessed with D&D. "He played Dungeons and Dragons and was obsessive with games of fantasy," the attorney was quoted as saying. "He became his fantasy. He was a ninja doing an honorable thing."
The moment I read it I burst out syurikens laughing!
