No it's not, don't do this. It's not going do anything but annoy your teachers and if you try to press the matter it could actually get you into trouble.
Also- NO. There is almost no part of that which is true. The Geneva convention generally:
1. Applies in war or acts of war.
2. doesn’t protect everyone all the time- one must qualify as a “protected person” even as a civilian
3. You are protected from such acts BY combatants.
Unless your teacher is an enemy of the state and the state is in conflict with your teacher- of a prisoner of a foreign nation- the Geneva convention doesn’t really apply to school.
Laws vary by state and even country- in general- there aren’t laws specifically forcing teachers to let you go at the bell. A school may have policies about teachers adhering to the Bell- but that’s it.
In broad terms- a teacher GENERALLY can’t hold you for a detention that would cause you to not be able to eat. They also generally cannot hold you past the time a bus or other transportation from school would take you. Other than that- there is a legal guardianship created between teacher and student in most countries. In effect- your parent, in their absence- grants a teacher certain parental rights as they pertain to enforcing discipline and educating you as well as keeping you safe.
There are laws which vary place to place that codify certain limits to that authority- but where not otherwise stated- a teacher is at their discretion. It’s a sort of “honor system” wherein if the parents are ok with it- generally it is ok. The two primary checks to a teachers power are their bosses (such as the principal) applying their supervision and discretion should they feel a teacher is overstepping their authority or scope- and parents.
If a parent feels that a teacher has overstepped their authority or done something which the parent does not approve of with that authority- the parent files a complaint. That complaint can start with the teacher or not- and escalate until either someone within the school administration rules with the parent and corrects the issue- or if the administration doesn’t satisfy the parent it can be taken to a legal forum or other arbitration.
So no, detention is not a war crime. That’s like saying you are committing a felony because you don’t have an emissions restriction system installed and were made after the 1970’s. Those laws apply to cars- not people, and the Geneva convention doesn’t apply to most students, teachers, and schools relationships with each other.
lol. I thought about mentioning that, but my comment was plenty long enough. But yes. In theory- and there are nuances to this- the Geneva convention applies to those involved in civil war- and to any conflict between sovereign states. That’s where it gets tricky though. A sovereign state doesn’t inherently require recognition to exist- but there are several factors required such as not relying on another state, having sovereignty over a territory, and being the sole government of a territory.
So the distinctions between war, civil war, terrorism, crime, sovereign state etc. are critical- and it would be very difficult to claim a school or classroom as a sovereign state- or to classify secession on that scale as civil war as opposed to rebellion etc.
An ultimate distinction might come down to the simple question of wether you control the school, and wether you rely on or are still under the power of the US government. To say the least the government likely wouldn’t give up the classroom as a possession- and to keep it would require unlawful actions- and likely fail if any force was used- at the least treason would be invoked. You could potentially remove treason by relinquishing citizenship prior to hostilities- but you’d most likely be treated as an unlawful combatant- which the Geneva convention doesn’t apply to the same as between states- and unlawful combatants are still subject to the laws of the state they transgress upon.
Tl:dr- if you played your cards right it could work- but would be tough. Ultimately though- you’d be trading detention for treason or other crimes which carry a more severe penalty and possibly losing your status as a citizen. Which takes us to a place of self defeating logic- the teacher works for the government (in the US at least) through the department of education. Recognizing their authority to give detention implies you are not a sovereign state because another government has authority in your borders not granted by treaty or agreement.
