The article is good, but I think it breaks down in the second half: it seems to me that the real takeaway here is that the Florida "stand your ground" law is a bad law (something people have been saying since the incident). Yes, people on the internet have been saying terrible and untrue things about Martin, but they've also been saying terrible and untrue things about Zimmermann. And the shooting mentioned at the end of the article is both tenuously connected and unlikely to end in an acquittal.
