"US Military Ordered 'Clandestine Burning' of Toxic Chemicals in Poor Neighborhoods: Study"

"Congress needs to throw cold water on the Pentagon's mad dash to burn toxic firefighting foam," which 'threatens the health of millions of Americans.'"

"New research conducted by environmental justice scholars at Vermont's Bennington College reveals that between 2016 and 2020, the U.S. military oversaw the 'clandestine burning' of more than 20 million pounds of Aqueous Fire Fighting Foam in low-income communities around the country—even though there is no evidence that incineration destroys the toxic 'forever chemicals' that make up the foam and are linked to a range of cancers, developmental disorders, immune dysfunction, and infertility."

Clandestine! Forever! Poor! Mad-dash!

All the correct "dog whistle" words.

"'dog whistle' is a coded message communicated through words or phrases commonly understood by a particular group of people, but not by others."

This is aqueous foam. Very efficient at fighting fuel fires. As might be present when an aircraft crashes.

True too the military has a history of producing products such as nerve gas the constituent elements of themselves are very toxic. Area 51 off limits to non-essential personnel for instance in large measure because of toxicity of the soil in some locations.
