Today's FOCUS report takes us to the plains and prairies of the American West. Over 70,000 mustang horses are now thought to roam free across a string of states, and the number is increasing.

Authorities have begun rounding up and rehousing the mustangs, but animal rights groups say that techniques used are too cruel. Our team has more.
