Question

Quizplus · Accepted Answer

Attorney-client privilege is designed to protect the confidentiality of communications between a client and their attorney. However, this privilege does not extend to communications that are in furtherance of a crime or fraud. In the context of counterterrorism, if there is a reasonable belief that the communication between a suspect and their attorney is being used to further acts of terrorism, officials may be allowed to monitor these communications under certain limited and strictly regulated circumstances to prevent harm. This is based on the principle that the privilege is not intended to protect communications that are part of the commission of a crime or an act of terrorism.
