Jean-Claude Mas, the head of the defunct Poly Implant Prothese, has a lot to answer for. He was arrested before dawn in France Thursday in connection with his company's use of industrial-grade silicone in tens of thousands of breast implants. The implants have become an international health scandal, with authorities struggling to settle on the proper response. German, Czech and French authorities say the implants should be removed, but Britain says there's not enough evidence that they're dangerous. Brazil says its government will fine insurance companies that refuse to pay for their removal.
