Need To Know: Fri., April 22, 2011

Need to Know teams up with ProPublica to examine the harmful effects of tainted drywall manufactured in China. We also look at a controversial plan in Detroit to "right-size" the city for easier management by paying residents to move out. And Jon Meacham examines a recent controversy over a pastor's remarks questioning the existence of hell.
