CT man charged for having posted about a toy gun on Facebook
It's blogged over at the Volokh Conspiracy. A person concerned about lax security at a school posted to Facebook, "“Maybe I have to walk in with Toy guns just to prove a point!”
Let's see, it's not a threat, but a question. It concerns a legal action, and a toy. It's not likely to cause the reader to take action that may result in injury to others ("falsely shouting fire in a crowded theater.") -- and the courts have long moved beyond that test anyway. Looks like a clear First Amendment violation to me.
