Now you only have to deal with that group of bullies who slowly build up resentments, and might end up paying your school one last visit.

There's also the civil litigation-heavy system to keep in mind, where teachers and lower-ranked admin workers get burned by superiors who have to please parents.

Seems like a slippery slope fallacy? Who says the person who got bullied relentlessly doesn't show up to pay one last visit? What an odd argument.

Seems like a decent approach to me tbh.

> "Who says the person who got bullied relentlessly doesn't show up to pay one last visit?"

Exactly! In both (the bully/the bully who once was bullied) cases, you'd still have to deal with these threats, as evidenced by relevant case histories. People are just a little too comfortable to jump to conclusions or create false dichotomies.

Someone that decided to shoot up a school, because they got kicked off the football team, when they could’ve just improved their behavior (and maybe demonstrated effort to improve their grades) - that kid’s reasoning is deeply flawed (even for a kid). Such kids are probably (hopefully) very rare, and I suspect they would’ve found some other reason to shoot up the school.

> There's also the civil litigation-heavy system to keep in mind, where teachers and lower-ranked admin workers get burned by superiors who have to please parents.

There should be more civil litigation for schools that allow bullying, and generally allow misbehaving students to disrupt others. If behaving kids aren’t learning because the teacher isn’t running the lesson because they’re dealing with a misbehaving kid whose parent threatened lawsuits, the behaving kids’ parents should team up and threaten the school (and maybe the misbehaving kid’s parent) with their own lawsuit.

Then maybe states can intervene and make frivolous lawsuits harder. Alternatively, they can effectively pay the parents (because they own the public schools who lose the lawsuits) to enroll their kids in private schools.

Very american concern, albeit not completely unique to that place. With that kind of logic, nothing ever gets done because of endless stream of what-ifs.

> "[...] nothing ever gets done because of endless stream of what-ifs."

This "endless stream of what-ifs" often enough translates to systemic "peculiarities" (e. g. ineffective bureaucracy, accountability diffusion, symptom-focus, political gaming, etc.) that result in exactly that: "nothing", let alone positive, ever gets done.
