“Words alone—even profane, offensive, and insulting ones—directed at police generally won't be enough for disorderly conduct charges. These words are protected under the First Amendment. However, the Supreme Court has decided that true threats and "
fighting words"—those that are likely to provoke someone into reacting violently or incite others to violence—are not protected speech. So, a defendant who yells profanities at an officer in a threatening manner or manner likely to provoke or incite violence can be charged with disorderly conduct (and perhaps other crimes).”
Why do you hate the 1st Amendment?
