BEAU Says Let's Talk About Ohio, troopers, and dogs....
Comment You left out an important piece in the video: The dog was not on him immediately. When the dog was released the dog ignored the trucker because he was no threat and ran towards the other cops. Then the dog handler redirected the dog back to the trucker who was on his knees at that point. -SNIP- This shows that this was not an accidental release and the dog being overly aggressive.
