> vehemently against social media monitoring by government agencies and warrantless wiretaps Does reading publicly published information constitute wiretapping? > we’ve seen plenty of anecdotes where concerning public postings were pointed out to authorities and nothing was done This is what I'm getting at-- responding to obviously-troubling social media posts seems entirely reasonable after the fact. Perhaps it is? But at the same time it carries an implication of law enforcement pre-emptively acting based on the content of public speech, which has its own worrying implications, as evidenced by the examples in the article. Earnest question: What's the legal boundary in other circumstances? Can/should law enforcement take action if a person uses a megaphone in the town square to announce they're going to use their AR-15 to kill all the $x people? If they published an op-ed in the local newspaper to the same effect? (If yes, how is facebook/twitter different from a town square / op-ed column?)
