YOUR AIR: 50 U.S.C. § 1520a
Congress barred the Secretary of Defense from “any test or experiment involving the use of a chemical agent or biological agent on a civilian population.” Then it wrote the exceptions. The ban “does not apply” to tests for medical, agricultural, industrial or research purposes, for protection against these weapons, or for “any law enforcement purpose, including any purpose related to riot control.”
The law requires informed consent from each test subject. Read it yourself and decide what those exceptions leave open.
