On this day in 1972, biological warfare was banned in a treaty signed by the United States and the Soviet Union, among other countries.

On this day in 2003, Congress passed the so-called “Amber Alert” bill. Named after a 9-year-old girl who was abducted in Arlington, Texas, and later found murdered, it provided a system for alerting the public and getting its help locating missing children.
