Animal rights activists are fighting the move claiming it violates existing federal law. The relevant statute is 16 U.S.C.1331. Its only a paragraph long and written in actual English, not some D.C legislative gobbledygook. This time I'm going to side with the animal activists.
Congress finds and declares that wild free-roaming horses and burros are living symbols of the historic and pioneer spirit of the West; that they contribute to the diversity of life forms within the Nation and enrich the lives of the American people; and that these horses and burros are fast disappearing from the American scene. It is the policy of Congress that wild free-roaming horses and burros shall be protected from capture, branding, harassment, or death; and to accomplish this they are to be considered in the area where presently found, as an integral part of the natural system of the public lands.
