Whether a prohibition on slaughter improves the welfare of the American horse population is the focus of this article. At the time it was written, winter of 2010-2011, a confluence of Federal and State legislative action had ended domestic slaughter. These actions are detailed in the body of this article. Since 2007, the legal status of horse slaughter remained static. Just as Sir Isaac Newton's first law of motion explained, an object at rest tends to stay at rest. Legislative inertia is the perspective from which this article was originally written. However, Newton's first law also stated that the object at rest will move when acted upon by an external pressure. The welfare of the American horse pressured a change in the legal status of horse slaughter in the United States.
