Initiating a legal battle is not for the faint of heart.  Few want to tangle with authority, and the kind of people that would implement + enforce such a thing (e.g. school administrators) are notorious for being petty and inflexible.  Moreover, they often have lots of legal backing for their actions (due to &quot;in loco parentis&quot; status) that are hard to pin down.<p>Most parents don&#x27;t have the resources for such a suit (or defense), and most students probably don&#x27;t want to risk getting suspended&#x2F;expelled or sent to a different school for being the one who sticks up for their rights.
