Today the Supreme Court  hears arguments in a case involving personal information found online. 

You know those sites online: just type in the first and last name and a mountain of personal data shows up. But what happens if some of that data turns out to be false? 

That's what happened to a Virginia man who is now suing the California-based company that came up with the data.

The case is now before the Supreme Court and it could have big implications for companies that rely on publicly-available data to share information about people.  We talk about it with Anupam Chander, professor of law at UC Davis.
