Virtual Child Porn: Is It Illegal?

pcosta writes "Today's LA Times has an article about a Supreme Court hearing on wheteher or not 'virtual' child porn created with computer generated images is illegal. In a previous ruling, the federal appeals court in San Francisco agreed 2-1 that the 1st Amendment prohibits the government from making it a crime to generate "images of fictitious children engaged in imaginary but explicit sexual conduct". But prosecutors said this kind of pornography can whet the appetite of pedophiles, and therefore is dangerous even if no real children are involved." This will be one of the major free speech cases of the year, and I think there's no telling how the Supreme Court will decide.
