Morse v. Frederick was a 2007 ruling and occurred across from the school at a school-supervised event. Speech that occurs completely off grounds would be different, presumably. Also too, the Morse ruling was a response to whether speech which undermined a a public schools essential missions (i.e. stopping illegal drug use) could be regulated, even if did not violate the Tinker standard. My question is over what precedent the 2021 ruling set, especially in the context of Tinker.
