Collective punishment

Why would you even vaguely consider grounding your daughter for this? This is pure unadulterated awesomeness.

It is also (as I understand it) true.

Students are considered civilians and therefore considered protected persons, under the 1949 Geneva Conventions, collective punishment is a war crime.

Article 33: Individual responsibility, collective penalties, pillage and reprisals

No protected person may be punished for an offense he or she has not personally committed. Collective penalties and likewise all measures of intimidation or of terrorism are prohibited.
