Used to be, when a high school student had a beef with a teacher, she talked about it on the phone or maybe passed a note in class, no expletives deleted. Now it gets posted on MySpace or Facebook, hopefully with privacy tools turned on. But privacy apparently wasn't of interest to Katherine Evans, who was suspended for starting a Facebook group about her English teacher entitled "Ms. Sarah Phelps [her English teacher] is the worst teacher I've ever met!" [Three other students joined to defend the teacher; Evans deleted it a few days later.] Now a freshman at the University of Florida, she is suing the principal of her former high school for suspending her, the Miami Herald reports. Her lawsuit claims the principal violated her First Amendment rights, "including the free exchange of ideas and opinions in the public arena" (she's seeking removal of the suspension penalty from her academic record and no money damages beyond legal fees). Here's further coverage.
