Not sure how I feel about this.
My mother raised 7 of us. I was the youngest. I would hear stories about how they each seen the rough side of the belt. She put the smack down on me a couple of times also. However all of these stories were when we were young. REAL young. I'm going to say nothing beyond the age of 9 at the most (one of my brothers was the hard headed one).
My point is I noticed after a certain age we got the point. There was no longer a need for the smack down. And I noticed later in life that my mother and Grandmother had a system that many police and law enforecement officers use. The system of 3:
1.The Statement (Stop)
2.The Warning (Stop or ____)
3.The Consequence (BAM)
AFTER #3 a couple of times I didn't have to go past 2 from the age of 7 on. Most of my brothers and sisters learned early and like I said only one brother needed a refresher of #3 at a later age. Not saying her way was the best way. I'm just saying by the time we reached this kids age (teenager) we knew better.
I'm not sure humilation will work for a teen.
Maybe this mothers technique will work, Maybe the teenager needed this to slap him back into reality that the world is not his friend and he needs to work hard to make it. I'm just not sure if this kind of Humiliation will slap him into reality or make him try to be harder ass to make up for being humilated in public.
