Your momma’s proposed narrative does not sound far fetched to me. Of course, we don’t know whether or not things happened that way. That’s why the parents should have been called.
In the past, when I read news stories of medical abuse, I always suspected there was more to the story. Why would any medical professional behave that way… 3 years ago, I was the victim of an incompetent nurse and a negligent doctor who instead of apologizing for making a life-threatening mistake, attempted to shame and bully me into silence. I was so baffled by the whole experience that I reached out to a few good friends (a nurse and 2 doctors) who said this behavior is unfortunately common, and patients would never know who the incompetent bullies are because the worst offenders seemingly have the best bedside manner.
Maybe you have to go through something like that to know you don’t give your blind allegiance to any human in any profession. I don’t know anyone who doesn’t recognize that others in their profession can at times be mistaken, incompetent, deceitful, power hungry, etc. Why would we assume ALL teachers are above reproach?
Maybe the student was coerced into confessing, maybe he wasn’t. We don’t know the answer because his true advocates (his parents) weren’t present. If the matter was important enough to have 3 teachers in the room to confront 1 child, then it was important enough to have parents present. With 3 teachers in the room against 1 student, there was a definite imbalance of power, no matter how great or well-intentioned the teachers may have been.
