Domestic surveillance refers to the monitoring of individuals, groups, or activities within a country's borders, typically conducted by government agencies or law enforcement. This surveillance can involve the use of various technologies, such as wiretapping, internet monitoring, CCTV cameras, and data collection from telecommunication networks. The primary goals are often to maintain national security, prevent crime, or gather intelligence. However, domestic surveillance can raise significant privacy and civil liberties concerns, especially if conducted without proper oversight or legal authorization. The balance between security and privacy remains a central debate in discussions about domestic surveillance.
