Chen calls in with an extraordinary tale of mysterious government agents detaining him at work. The Baron writes in to ask about ancient metal from the stars. Over on Instagram, an anonymous source gives their first-hand experience working in the world of precrime... and how the technology is much further along than the average person might assume. (That last one, in fact, was so frightening that we decided to end on some jokes.) All this and more in this week's listener mail. They don’t want you to read our book.
