Perfect example of the absolute IDIOCY of our government. Huge numbers of mustangs would be in the hands of private owners who WANT them yet aren't willing to jump through the myriad hoops put in place by the government in order to obtain one. Make it incredibly difficult to get one, then complain that there are too many. Their solution? Kill 'em. Absolute shame.

There very well may be a lot of restrictions... the only one I have heard that is hard for people to meet is the fencing requirement, which is not an asthetic demand, but a practical one. Wild horses can't just be turned out in electric or barbed wire fences. The fences won't hold them, and the horse may not survive the encounter.
IMHO, there are not a lot of horsemen who really want or can handle mustangs... they are a specialty that I can imagine there is limited demand for. There is demand, but I fear there will always be more horses than homes, even after this (hopefully) one-time bubble of overpopulation is eliminated.
