Attack
On Monday March 20, 1995, five members of Aum Shinrikyo launched a chemical attack on the Tokyo Metro, one of the world's busiest commuter transport systems, at the peak of the morning rush hour. The chemical agent used, liquid sarin, was contained in plastic bags which each team then wrapped in newspaper. Each perpetrator carried two packets of sarin totaling approximately 900 millilitres of sarin, except Yasuo Hayashi, who carried three bags. Aum originally planned to spread the sarin as an aerosol but did not follow through with it. A single drop of sarin the size of a pinhead can kill an adult.
Carrying their packets of sarin and umbrellas with sharpened tips, the perpetrators boarded their appointed trains. At prearranged stations, the sarin packets were dropped and punctured several times with the sharpened tip of the umbrellas. The men then got off the train and exited the station to meet his accomplice with a car. By leaving the punctured packets on the floor, the sarin was allowed to leak out into the train car and stations. This sarin affected passengers, subway workers, and those who came into contact with them. Sarin is the most volatile of the nerve agents, which means that it can quickly and easily evaporate from a liquid into a vapor and spread into the environment. People can be exposed to the vapor even if they do not come in contact with the liquid form of sarin. Because it evaporates so quickly, sarin presents an immediate but short-lived threat.

—Elizabeth Blackwell (1821–1910)
“When Religion and Royalty are swept away, the people will attack the great, and after the great, they will fall upon the rich.”
