    #10 - A Dangerous Business

    Loading...
    S21:E9

    Each year, six thousand Americans lose their lives on the job. Tens of thousands more are seriously injured or exposed to deadly poisons and carcinogens in the workplace. Yet if one of those workers dies on the job due to a company's willful disregard for federal safety regulations, the maximum penalty his employer faces is just six months in prison. Are America's workplace safety laws tough enough? And are companies being held responsible for protecting the safety of their employees? FRONTLINE investigates workplace safety in one of America's most dangerous industries.

    #11 - Faith and Doubt at Ground Zero

    Loading...
    S21:E1

    For many Americans, the most difficult questions about 9/11 were not about politics, military strategy or homeland security. They were questions about God, about evil and about the potential for darkness within religion itself. What was it we saw on Sept. 11? Was it the true face of evil? Was it the face of religion? And where, if one is a believer, was God on that tragic morning?
