Civil liberties often conflict with national security measures, particularly during crises. Governments may impose surveillance, censorship, or limitations on free speech to protect citizens, which can infringe on individual rights. This tension raises critical questions about the maintenance of a free society versus the need for safety. Legal frameworks, such as the USA PATRIOT Act, illustrate how national security concerns can shift public policy, leading to significant debates about privacy and civil rights. Balancing these interests is an ongoing challenge in a vibrant democracy.
