"When it comes to traffic in material that violates the Copyright Act, the policy of the United States is embedded in the FBI warning we see at the start of every lawfully purchased or rented video: Infringers are to be stopped and prosecuted."
There's a lot more involved in his opinion, which really focuses on credit card companies profiting from infringement -- but considering how he much he writes against those who help others infringe, it's probably not a wise idea that he was out there sharing music files himself.
However, to be fair, as the details come out, this whole thing is quite clearly a witch hunt by someone who seriously dislikes the judge. As we noted when the story broke, it's perfectly ridiculous to try to suggest this makes him any less qualified to judge cases. And, indeed, as the details come out about the content on his server, it's becoming clear that it is, as he noted "funny" stuff. It's all basically the sort of silly viral content that gets passed around all the time, much more for the amusement factor than any sort of titillation.
This post certainly isn't to slam Kozinski, who seems like a genuinely thoughtful judge -- with a sense of humor to boot (he famously nominated himself for a mocking "Judicial Hottie" contest run by a blog, noting: "While I think the list of female candidates is excellent, the list of male candidates is, frankly, lacking. And what it's lacking is me.... I have it on very good authority that discerning females and gay men find graying, pudgy, middle-aged men with an accent close to Gov. Schwarzenegger's almost totally irresistible." The fact that he was also sharing MP3s, again, is just yet another reminder that, contrary to the entertainment's claim that "education" will solve music sharing, many people just think it's perfectly natural and reasonable to share a song with some friends.
