Listen carefully. Hear that sound? That's your constitutional rights being chipped away.
I'm not prepared to write a comment on the Supreme Court's decision in Hiibel v. Sixth Judicial Dist. Ct. of Nevada. Mostly because I don't have the time.
What you need to know is that if you're stopped by the police, and they ask for your name, you've gotta tell them. Otherwise you can be arrested (depending on your state's statute). Just for not telling them. Scary, right?
So now I've got to stop telling my clients "Don't talk to cops," and instead tell them, "Consult the local statute, and, if in doubt, give your name." Not quite as catchy, really.
If you'd like to read more commentary on the decision, I direct you to other law bloggers who posted on the subject, including CrimLaw, The Volokh Conspiracy, The Shout and SCOTUSblog.
