Three of those were people directly and clearly threatening to kill a police officer. A fourth one was saying she'd kill a police officer if she was pulled over, and got a "disorderly conduct" charge which may very well get thrown out. She was arrested and immediately released. Freedom of speech is working fine aside from NSLs.
