clear and present danger
/ˌklɪər ən ˌpreznt ˈdeɪndʒə(r)/
/ˌklɪr ən ˌpreznt ˈdeɪndʒər/
- the expression used by the US Supreme Court to indicate a situation in which complete freedom of speech is not a person's legal right. No one has a right to say something that would cause a clear (= obvious) and present (= immediate) danger to other people. As an example, the freedom of speech protected by the First Amendment does not allow a person to shout 'Fire' in a crowded theatre.
明确和当前的危险：美国最高法院用来表示完全言论自由不是人的合法权利的情况。没有人有权说出可能对他人造成明显和当前危险的言论。例如，《第一修正案》保护的言论自由不允许一个人在拥挤的剧院里大喊“大火”。
