Tim McGraw is a rodeo supporter who has performed at many rodeos and is clearly a fan of this kind of animal abuse
That's pretty rude. I can't get over people who make these statements up. This just sounds like another PETA organization to me. Accidents happen - and yes, these accidents shouldn't have happened - but they're not unusual accidents.

I've heard of lots of times where a horse "missteps" and injures itself so badly, it needs to be put down. If a horse steps on it's on rope/bridle/whatever, it can break it's jaw.

They should have disallowed an event so inherently dangerous and uncontrollable from taking place to begin with
Many movies have wild horse races - tons of older westen movies have many in their movies.

Maybe AHA should have stepped in sooner - they could have prevented these deaths.
