Draft for bullet point:
In 1950, the US Navy sprayed bacteria over the San Fransisco Bay Area during Operation Sea-Spray, one of the largest human experiments in history. The residents of the area were not informed, making the event a serious violation of the Nuremberg Code on medical ethics. In the following month, 11 residents checked in at a local hospital with a rare urinary tract infection, and the area saw a spike in pneumonia cases. This was one of numerous open-air tests of biological agents conducted by the US Armed Forces during the Cold War.
