Throughout history, the U.S. federal government has authorized, carried out, and funded biological warfare against its own citizens. As part of the U.S. attacks on its own people and as a national security protocol, "gangstalking" involves using bacteria as one method of attacking targeted individuals. This despicable weapon aims to destabilize the mental and physical stability of the targeted individual, making it difficult for them to resist the "gangstalking" threat, which they would have been able to do if they were healthy.

That's all.
Please also see the following information regarding the U.S. Army and CIA programs.
"Operation Sea-Spray"
"Operation Big City"
"Bacteriological experiments at airports and bus terminals"
Other examples include biological warfare tests conducted against American citizens under the guise of "experiments."
In the course of human events, the United States federal government has authorized, implemented, and financed germ warfare against its citizens. A part of the United States of America's war on its citizens, also known as gangstalking, which is an American national security protocol, the attack mechanism against its targeted individuals is comprised of the hurling of (germs) at targeted persons. This thuggish weapon is aimed at destabilizing the targeted individuals so that they cannot readily fight the gangstalking menace as they would when they are well.
