When I was in elementary school, I really hated it when teachers punished the class for the bad behavior of an individual. I wondered what the class was supposed to do to encourage bad actors to change their behavior.
Rowdies didn’t want kindness or emotional support from classmates. They just wanted to be disruptive. Some in the class could threaten them, or actually beat them up, but that would attract the truancy authorities to “the good guys,” and make the thug a victim, likely perpetuating bad behavior.
The current debate over more gun control and red flag laws calls to mind that long-ago classroom.
