On this bonus episode, I go into some of the history between the LAPD police commission and the Stop LAPD Spying Coalition, and feature some of the tape from the Central station CSOC protest that didn't make it into the episode, including some creepy stuff that happened toward the end of the protest. I then talk to Sarah Brayne about the possibility of using surveillance technology to monitor the police themselves.

Predictive policing technology is spreading across the country, and Los Angeles is the epicenter. A small group of LA activists are in a lopsided campaign against billions of dollars in city, federal, and Silicon Valley money using algorithms to predict where and when the next crime is going to occur, and even who the perpetrators are going to be. Barry embeds with the Stop LAPD Spying coalition for a week in Skid Row and investigates how state-of-the-art predictive policing programs work. He then talks to sociologists and philosophers about how big data is changing the relationship between police and the communities they serve. We then turn to the justice of using statistical predictions for the purposes of profiling and police intervention. This is part 1 of 2 on the use of statistical algorithms in criminal justice. Guest voices include the LAPD police commissioners, Hamid Khan, Jamie Garcia, Sarah Brayne, Flora Salim, and Renee Bolinger.To get an ad-free feed for this and all other Slate podcasts, and to get bonus content for this season, sign up for Slate Plus.

Do people of opposing political parties believe in different facts? The mantra at the moment is that they do, because of media echo chambers, motivated reasoning, and ideological blindspots. But a more careful look reveals a different answer, with perhaps even more startling consequences. This week we follow two conservative Republicans who consumed a liberal newsfeed for two weeks, and we look at the empirical and philosophical problem of the way partisanship affects belief in facts. Guest voices include Janalee Tobias, Trent Loos, philosophers Daniel Wodak and Eric Schwitzgebel, and political scientist John G. Bullock. The episode is brought to you by the Great Courses Plus.

In ordinary life, it is usually not hard to know who you are and who you used to be. For a small group of children around the world, their knowledge seems to conflict with what modern science believes is possible.

We delve into the strange philosophy and science of personal identity, quantum physics, and belief in the afterlife.

When Lori Lieberman was 19 years old, she went to a concert of a singer she didn't know, and ended up writing a poem that would become one of the greatest cover songs of all time. This week we are going to look at the art of covering in popular music, and how that art marked the conversion from a classical model of musical aesthetics to a contemporary one. Popular music in the modern era is metaphysically complex due to the fact that its listeners make very fine-grained judgments about artistic merit and quality. We are going to talk about the stories behind some of the most iconic cover songs in the rock era, analyze an iconic song with Switched on Pop podcast host Nate Sloan, and transform all of it into the philosophy of music. Guests include Ray Padgett, Nate Sloan, Cristyn Magnus, and P.D. Magnus. Learn more about your ad choices. Visit megaphone.fm/adchoices

Guest voices include Nick Riggle, Leah Borromeo, Rowland Atkinson, Victor Callister, and Richard Rowland. Learn more about your ad choices. Visit megaphone.fm/adchoices
