What is one civic duty of American citizens under the law?

One civic duty of American citizens under the law is jury duty. Serving on a jury is a fundamental aspect of the American legal system, whereby citizens are called upon to participate in the judicial process by listening to the evidence presented in a case and making a decision based on that evidence. This participation ensures that the judicial system remains fair and that individuals are judged by a group of their peers, upholding the principle of a fair trial as guaranteed by the Constitution.

Engaging in jury duty is a legal obligation; citizens are required to report when summoned, emphasizing the importance placed on civic involvement in maintaining justice in society. Unlike other options provided, which may be encouraged or beneficial to society, serving on a jury is mandated by law, highlighting the unique role it plays in American civic duties.
