""In carrying out searches and other disciplinary functions pursuant to such policies, school officials act as representatives of the State, not merely as surrogates for the parents, and they cannot claim the parents' immunity from the strictures of the Fourth Amendment."" (NJ v TLO) Meaning: schools have the right (and responsibility) to take steps necessary for the safety of children, but those rights are rather limited compared to those of parents, because they must also satisfy the limits set by constitution for all acts of the state and its representative. Banning books is an excellent example since it is almost the textbook definition of a restriction of free speech at the same time as having exceptionally weak arguments for its necessity, ostensibly to prevent psychological harms, which is a dubious concept to begin with.
