For years American military forces burned the by-products of their activities at sites called burn pits. Medical waste, discarded shells and bullets, rubber, plastic, and all sorts of other toxic materials were burned next to overseas military bases. The fumes were known to cause extremely virulent forms of cancer; something the U.S. military establishment denied for a long time. On this episode of the Whistleblowers John Kiriakou sits down with former marine Joseph Hickman to discuss his work and his book detailing the horrors of the burn pits.
