On March 20, 1995, Aum Shinrikyō, a fanatical Japanese religious cult, released sarin, a deadly nerve gas, on five subway trains during Tokyo’s early-morning rush hour. A male cult member boarded each of the trains carrying two or three small plastic bags covered with newspaper and, at an agreed-upon time, removed the newspaper and punctured the bags with a sharpened umbrella tip. On the trains, in the stations where they stopped, and at the station exits, people coughed, choked, experienced convulsions, and collapsed. Eleven were killed and up to five thousand injured. Had Aum succeeded in producing a purer form of the gas, the deaths could have been in the thousands or hundreds of thousands. For sarin, produced originally by the Nazis, is among the most lethal of chemical weapons. Those releasing it on the trains understood themselves to be acting on behalf of their guru and his vast plan for human salvation.
