schools are not an open public forum in which the full scope of the constitution applies. . . i could give u a detailed answer because i just learned this in con law II for law school. . .
simlpy said, the govt. has a "significant, compelling interest" in inhibiting what can be said and done at public schools. . . the courts apply a balancing test, in which they said the govt.'s interests outweigh those of the students to enjoy freedom of speech. . . students still have some constitutional protections, and freedoms, but it's limited. . . same as prisons. . .
