According to the laws and social ethics of most countries and regions, if you accidentally hear information that may endanger public safety in a public place, you are usually obliged to report it to the relevant authorities. This responsibility is based on the consideration of protecting the safety of others and the public interest. In many cases, the law will stipulate "mandatory reporting", that is, if you know or have reasonable grounds to believe that certain information may pose a threat to public safety, you should report it to the relevant authorities. In this case, the leaked information is generally considered to be for the protection of public safety rather than intentional disclosure of private information. Of course, the specific legal responsibilities may vary from country to country, and it is recommended to consult a legal expert or local relevant agency in actual circumstances to understand your specific responsibilities and protection measures. In short, it is very important to prioritize public safety.
