Last October, a recently fired police officer walked into his stepson’s nursery school in the remote northeast of Thailand and, in under 30 minutes, killed 23 children and two teachers. Panya Kamrab hacked some of his victims to death with a sugar-cane machete and shot others point blank with a pistol, including three local government employees eating lunch outside the school. The rampage, which left a total of 36 dead, ranks as the worst in Thai history and one of the worst in the world.
