Last month, I had two blog posts about a particularly insane lawsuit being pushed by the Justice Department against a computer security researcher, Justin Shafer. As we explained, the arrest and prosecution of Shafer appeared to be the result of a truly ridiculous vendetta against Shafer by the FBI because Shafer got angry over a previous (and totally misguided) decision to raid his home, after he properly disclosed security problems involving some dental practice software. It seems clear that Shafer never should have been arrested (and never should have had the FBI raid his house three times over just a few months). Of course, what first brought the case to my attention was an even more ridiculous part of the story, in which the DOJ had sent a subpoena to Twitter demanding basically all info on five Twitter users — even though two of them don‘t hide their identity — because Shafer tweeted a smiley emoji at them.
