Preview: In the business of horse slaughter

(CBS News) Horses are a major part of American culture. Cowboys rode them to tame the West, toy horses are a staple in kids' bedrooms and many raise them as companions to ride and race. But unlike other cultures around the world, Americans have an aversion to treating horses as livestock fit for slaughter and human consumption.

After putting a halt to horse slaughter in 2006, Congress lifted the ban last year, which put one small businessman, Rick de los Santos, in the crosshairs of a culture war.

Be sure to tune in to "CBS This Morning" Friday when CBS News Correspondent Bill Whitaker will share de los Santos' story.
