Civil liberties erosion refers to the gradual weakening or infringement of individual rights and freedoms that are protected by law, often justified by national security concerns or public safety. This process can occur through legislation, executive actions, or judicial decisions that limit the scope of these liberties, leading to a society where rights such as due process, freedom of speech, and privacy are compromised. The Guantanamo Bay detention camp serves as a stark example of civil liberties erosion, highlighting how the pursuit of security can overshadow fundamental rights.
