Civil and political rights
The freedom of speech - Article 19 of the ICCPR guarantees the right to free expression. But it is a derogable right, meaning it can be regulated if that regulation serves a vital public interest. An example is the US Supreme Court Justice Oliver Wendell Holmes, Jr. in the case Schenck v. United States (1919). The case was about limiting free speech during wartime to serve the greater good. He is famously quoted as saying: "The most stringent protection of free speech would not protect a man in falsely shouting fire in a theatre and causing a panic."
