Is sunscreen the snake oil of the 21st century? Sam Rudman, a lawyer who is leading a class-action charge against five sunscreen sellers says it is.

Geezer is with the docs. He argues that most claims made about the dangers of skin cancer are not in dispute. Listen to a podcast about the lawsuit on Marketplace.
