The horses made this story
It turns out nearby the horse farm if their is a lot of marijuana growing and those cops want to get rid of it and burn it all down even the horses get High on that much pot smoke.
They can be well trained and breed but they have a mind of there own and they will carry you far and away fast to get past all that smoke.
So when the smoke clears and you got a horse and a rider not in the right/write place
That horse is smarter than you and preserved and persevered to try to make sure that the message was coming through loud and clear because instinctual animals OBEY God much better than humans. They do not have free choice.
