Jimmy Jamz, are your parents siblings?  
A 1971 law states:
“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.” Defined as… ” the amount of land the amount of land necessary to sustain an existing herd or herds of wild free-roaming horses and burros, which does not exceed their known territorial limits, and which is devoted principally but not necessarily exclusively to their welfare…”
With no legal basis, 95% of the land that by law was to be “devoted principally” to the welfare of the wild horses and burros was leased to for-profit cattle and sheep ranchers. To the tune of 150 cattle and sheep to one horse or burro. That is illegal. Got it?
