Much of Britain was exposed to bacteria sprayed in secret trials

The Ministry of Defence turned large parts of the country into a giant laboratory to conduct a series of secret germ warfare tests on the public.
A government report just released provides for the first time a comprehensive official history of Britain's biological weapons trials between 1940 and 1979.
Many of these tests involved releasing potentially dangerous chemicals and micro-organisms over vast swaths of the population without the public being told...


Similar tests were done in California in the United States - but hey - trust your government - if you don't your a tin-foil cap wearing conspiracy not - because after all - there are no conspiracies and your government would never do anything to harm you!
