I want to know the answer to the following question:
When was the supposed germ warfare testing taking place?
All the background I'm provided with is that "A government report covered by the Guardian in 2002 indicates that between 1940 and 1979, 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" and many of these tests "involved releasing potentially dangerous chemicals and micro-organisms over vast swaths of the population without the public being told.". Is that enough to answer the question?
