In a major and muscular First Amendment ruling, the Supreme Court on Tuesday struck down a federal law that made it a crime to create or sell dogfight videos and other depictions of animal cruelty.
The case arose from the prosecution of Robert J. Stevens, an author and small-time film producer who presented himself as an authority on pit bulls. He did not participate in dogfights, but he did compile and sell videotapes showing the fights, and he received a 37-month sentence under a 1999 federal law that bans trafficking in “depictions of animal cruelty.”
When President Bill Clinton signed the bill, he expressed reservations, prompted by the First Amendment, and instructed the Justice Department to limit prosecutions to “wanton cruelty to animals designed to appeal to a prurient interest in sex.” But since then, the government has used the law in several prosecutions for trafficking in dogfighting videos.
Not a very surprising decision, and I'm not sure it's "major" or "muscular." But that's just reading the article. I haven't browsed the ruling itself yet.
