Gotta disagree with you on this one. These "officers" are completely out of control.
No you really need to see the whole video. I have. The male officer is saying “My dad would have beat my butt five times before I got home had I done something like this” or something like that.
That is what the officers meant.
I tend to agree with you. The kid needed a strong course-correction. But that should only be done by the parents, or with the parents’ permission.
