How do you define the right to free speech? Some would argue it means being allowed to say what you believe, even when it's not popular. Others would say it means getting a good look at what kind of prescriptions that your doctor has given you. At least, that's the argument being made in a Supreme Court case today, in which company IMS Health will make a case for allowing pharmaceutical companies to get a gander at just what kind of prescriptions you're picking up at the pharmacy for marketing purposes.
