Free speech versus the school authorities

Well, this isn't surprising, but it is rather depressing to read:

Kieran King, a Canadian 10th-grader, did some research and discovered that marijuana is not as bad as his government makes it out to be. When he shared this information with his friends at the Wawota Parkland School in Saskatchewan, King says, the school's principal, Susan Wilson, accused him of selling pot and threatened to call the cops. Outraged at the principal's intimidation, King organized a student walkout to protest what he saw as a violation of his right to free speech. Wilson responded by locking down the school and suspending the 15-year-old for three days, which will force him to miss his final exams. Not your average pothead, King says he's never seen marijuana, let alone smoked or sold it. "The main purpose [of the protest] wasn't cannabis," he told the Regina Leader-Post. "It was the defense of the freedom of speech. I believe we have a right to freedom of expression."

Call me pessimistic, but I don't see this ending well.
