National security policies often impact civil liberties as governments prioritize the protection of citizens against threats. In response to terror acts or perceived risks, authorities may enact laws limiting freedoms such as speech, assembly, and privacy. While these measures aim to enhance safety, they can lead to controversial debates about the balance between security and individual rights. For example, surveillance practices may be justified by officials as necessary for national security, yet they raise significant concerns regarding personal freedom and legal protections. This tension necessitates careful scrutiny to uphold democratic principles while addressing genuine security needs.
