Four more have been murdered by a teen with an assault-style rifle - many more were injured - at Apalachee High School in Winder, GA. Still, this episode gives us a glimmer of hope: specialists in “behavioral threat assessment” have been quietly trying to spot potential killers for decades, in places from schools and companies to government agencies - and the latest carnage could probably have been avoided if authorities had followed their manual. Our guests, practitioners Monique Boudreaux and Matt Talbot, say everybody in America needs to help them instead of looking the other way.

Lee Bollinger, who was president of Columbia University and the University of Michigan, predicts that the number of black students at many colleges will plummet to low levels they haven't seen since the 60s and 70s. He says Chief Justice John Roberts and the other Republican extremists on the Court misinterpret the Constitution. And as for the belief that under affirmative action, college officials generally admitted blacks who weren't qualified? Lee says: Not true.

Trump, the Republican party and Project 2025 are echoing Orbán's autocratic playbook - along with strategies of other leaders who got elected democratically and then turned their nations into autocracies. Key steps: pack courts and agencies with their cronies, slander and intimidate the media, and denigrate their opponents as "evil" and "vermin." Harvard professor Steven Levitsky, co-author of How Democracies Die and Tyranny of the Minority, tells us why it could take years to rescue America's democracy - even if Trump loses the upcoming election.

Sesame Street changed TV by using music to help kids learn how to spell and how to share. Singer-songwriter Anya Rose and the group Ants on a Log write social action songs to help children in primary school learn edgier lessons, about problems from environmental pollution to racist and sexist behavior - inspired in part by 60s satirist Tom Lehrer. After hearing these tunes, the 9-year-olds in your family might feel inspired to research a problem in your own neighborhood - and then write your members of Congress about it!

Now that Judge David S. Tatel has retired from the U.S. Court of Appeals for the D.C. Circuit, he feels freer to warn us all: the Supreme Court is threatening America's democracy by inventing spurious legal doctrines and grabbing more power for itself. There are also lighter moments in this revealing interview, as David pulls the curtain aside and tells us how the judges on this powerful court really do their work. Spoiler alert #1: It used to involve a red children's sand pail. Spoiler alert #2: Because David is blind, he used to hire "readers" who rattled off every word of laws, books and briefs out loud to him, at such mind-boggling speeds that most people couldn't understand them.

David Tatel - who retired recently from the U.S. Court of Appeals - has led what he calls a "braided life" that intertwines hardship and accomplishment. With his wife, Edie, he describes how he struggled to hide his gradual loss of sight from friends and colleagues alike - including tricks like counting rows and seats in a movie theater and following the clicks of high heels. Meanwhile, David became an accomplished lawyer who fought landmark civil rights cases. You can read their full story in David's new book, Vision: A Memoir of Blindness and Justice. David will return in Part 2 to take us behind the scenes of the second most important court in the nation.

Lewis Simon's Pulitzer Prize-winning reporting, in collaboration with colleagues, helped spark an international scandal and topple a corrupt dictator in the Philippines; he tells us in this episode how they did it. Lew also gives us remarkable insight into how he could do his work - taking notes as people got beaten to death and blown up in front of him, in countries like Cambodia and Bangladesh - and survive emotionally. And finally, a roving correspondent talks honestly about the toll that constant traveling took on his spouse. After hearing Lew, you might think differently about what reporters face when they tell you the latest from Ukraine and the Middle East.

Next time you hear details of the horrific wars in Ukraine and Gaza, think about how you're learning them: journalists are risking their lives to report from the front lines. Lewis Simons won the Pulitzer Prize during decades of reporting on the Vietnam war and other conflicts across Asia. He lived by a motto: "Whatever the threat or danger, I had to be there."
