Secret Cold War tests in St. Louis were performed by the United States military. Click here for the story.
An excerpt from the story:
In the mid-1950s, and again a decade later, the Army used motorized blowers atop a low-income housing high-rise, at schools and from the backs of station wagons to send a potentially dangerous compound into the already-hazy air in predominantly black areas of St. Louis.
Local officials were told at the time that the government was testing a smoke screen that could shield St. Louis from aerial observation in case the Russians attacked.
But in 1994, the government said the tests were part of a biological weapons program and St. Louis was chosen because it bore some resemblance to Russian cities that the U.S. might attack. The material being sprayed was zinc cadmium sulfide, a fine fluorescent powder.
A separate, but equally swell story on Slate describes how the U.S. government poisoned Americans’ alcohol during prohibition. Click here for story.
Here is an excerpt:
Frustrated that people continued to consume so much alcohol even after it was banned, federal officials had decided to try a different kind of enforcement. They ordered the poisoning of industrial alcohols manufactured in the United States, products regularly stolen by bootleggers and resold as drinkable spirits. The idea was to scare people into giving up illicit drinking. Instead, by the time Prohibition ended in 1933, the federal poisoning program, by some estimates, had killed at least 10,000 people.
