With the Miami real estate market booming, why were some residents being left out in the cold? With an innovative tax on commercial real estate transactions, money was flowing into the Miami-Dade Housing Agency, the body charged with building affordable housing. But there was a problem: a lot of money was going out, but not a lot of houses were being built. Reporter Debbie Cenziper of THE MIAMI HERALD goes inside the agency's own incomplete records, fills in the gaps, and connects the dots -- exposing mismanagement and an insider's club where backs were scratched and palms were greased. And watch the full episode when it premieres online, Wednesday, July 25, at 12 noon ET. (Or check your local listings for broadcast dates on PBS nationwide, beginning Friday, July 27.)
