America's prisons house a "staggering number" of convicts who didn't commit the crime but said under duress that they did - so says our guest, lawyer Alan Hirsch, who testifies in trials across the country as one of the leading expert witnesses on false confessions. He took the stand not long ago in the chilling case of teenager Brooke Skylar Richardson, who was pressured by police to say that she'd murdered her baby, who was actually stillborn, and then burned the body; the jury acquitted her after forensic studies showed that the baby had never been burned at all. Alan says one problem is that police learn to lie about evidence and use clever interrogation methods that break down suspects' defenses, whether they're actually guilty or not. Some states are requiring police to film their whole interrogations - a step forward but not a panacea.

When you learned ​in school about the fabled drama of Robert E. Peary and Frederick Cook​ - how they raced each other to be the first explorer to reach the North Pole - did your teachers explain that this was an early example where public figures lied to gain glory? oth The New York Times and New York Herald enabled them, by spreading the explorers' fake news - although critics still debate whether the publishers knew the stories were fake or didn't bother to corroborate the explorers' stories. Journalist Darrell Hartman tells us life and death tales from his fascinating book, Battle of Ink and Ice, that shed light on the perils of vanity and competition for fame and profit.

An English teacher at Middletown High School in New York State gave students video cameras back in the 1990s, and told them to tell compelling stories. Result: They uncovered illegal dumping of toxic wastes tied to the mob, and then made films about it - which shook the community and triggered government investigations. A documentary about their real-life drama, Teenage Wasteland, is making the rounds of film festivals and generating rave reviews. The teacher who guided the project, Fred Isseks, joins us with two of his former student investigators, Rachel Raimist and Jeff Dutemple. And they say the most important outcome was bigger than exposing illegal dumping: They learned how to ask tough questions, challenge government officials, and sort facts from lies.
