Long before Hollywood imagined the Wild West, Los Angeles was a real frontier town of gunslingers, lynch mobs, and smoke-belching locomotives. This episode examines L.A.'s efforts to reckon with its violent past by examining hanging trees, remnants of vigilant justice; the massacre of eighteen Chinese immigrants that took place in 1871 near what is now Olvera Street; and railroad promotional campaigns that painted a picture of Los Angeles as a verdant paradise.
