The full story is told by the Comic Book Legal Defense Fund in a press release published by Comic Book Resources. The long and short of it:
Mr. Handley’s case began in May 2006 when he received an express mail package from Japan that contained seven Japanese comic books. That package was intercepted by the Postal Inspector, who applied for a search warrant after determining that the package contained cartoon images of objectionable content.
And for that, he might go to jail for 20 years. I applaud Random House and the Comic Book Legal Defense Fund for taking an important and necessary stand on this because the potential consequences for it are scary for fandom, large parts of which exist in a text and art based medium.
