I have experience in this. The Supreme Court of the United States has ruled on it. If it’s open comment time, they cannot censor except for obscene or threatening speech. All they can do is set a time limit. Don’t cuss or make violent threats and you’re good. If they censor you it’s an open and shut civil rights case.

If it’s a public hearing for a specific matter, they can restrict comment to that topic.

Seems like an opportunity for malicious compliance …. Perhaps everyone can speak up against stifling public input “on matters like F*ck cameras”
