The following is from the United States Code, Title 50, Chapter 32. It allows the Department of Defense to utilize unsuspecting citizen populations as guinea pigs in the testing of chemical and biological warfare agents! 

§ 1520. Use of human subjects for testing of chemical or biological agents by Department of Defense; accounting to Congressional committees with respect to experiments and studies; notification of local civilian officials:

• (a) Not later than thirty days after final approval within the Department of Defense of plans for any experiment or study to be conducted by the Department of Defense, whether directly or under contract, involving the use of human subjects for the testing of chemical or biological agents, the Secretary of Defense shall supply the Committees on Armed Services of the Senate and House of Representatives with a full accounting of such plans for such experiment or study, and such experiment or study may then be conducted only after the expiration of the thirty-day period beginning on the date such accounting is received by such committees. 

  (b) (1) The Secretary of Defense may not conduct any test or experiment involving the use of any chemical or biological agent on civilian populations unless local civilian officials in the area in which the test or experiment is to be conducted are notified in advance of such test or experiment, and such test or experiment may then be conducted only after the expiration of the thirty-day period beginning on the date of such notification. 

  (2) Paragraph (1) shall apply to tests and experiments conducted by Department of Defense personnel and tests and experiments conducted on behalf of the Department of Defense by contractors.
