I know just what you mean (and this is our own government): witness:
Cities were unwittingly used as laboratories to test aerosolization and dispersal methods; Aspergillus fumigatus, B. subtilis var. globigii, and Serratia marcescens were used as simulants and released during experiments in New York City, San Francisco, and other sites. Concerns regarding potential public health hazards of simulant studies were raised after an outbreak of nosocomial S. marcescens (formerly Chromobacterium prodigiosum) urinary tract infections at Stanford University Hospital between September 1950 and February 1951, following covert experiments using S. marcescens as a simulant in San Francisco.
I was researching petri dish air sampling today to test my father's home. I had to read the article twice about the testing in the 1950's with balloons filled with S. marcescens released over San Francisco that caused the urinary tract infections and pneumonia. Outrageous!
