I'm thinking of tweeting the video of a kid who flipped off our Ring camera while delivering a Catholic church/school "newspaper"
I am not sure I understand. What do you think will happen to him?
The kid will be punished and expelled.
I understand you were appalled by his untoward gesture, but do you really think getting him expelled from school is called for? Think back at your own behavior. Have you ever done anything a little irreverent?
It was rude and deserves punishment.
Usually people will overlook a small mistake rather than risk harming someone's education.
