I just don't want to hurt the schools insurance too much as I have a strong sense of responsibility and personal investment in the schools wellbeing.
Another thought: if you sue and it goes to trial, can it lead to legal action against the school, staff, etc. because of the negligence? Can it lead to discussion about individual people's actions and how that impacted the outcome? If there is real negligence, can people be arrested, charged, etc.? I have no experience, just wondering out loud.
