Mustang Horses

In some places, there are mustang roundups. But sometimes, in order to get rid of all the wild horses, they kill them! Sometimes they shoot them from helicopters, run them over cliffs, or chase them with cars until they drop dead from exaustion! It's wrong, and it hurts to know that people would do things like this just to clear they're land! This horse murder should stop, but most people refuse to even acknowledge it!
