Surveillance technologies and Fourth Amendment limits
Surveillance technologies refer to tools and systems used by authorities to monitor individuals’ activities, often for security or law enforcement purposes. The Fourth Amendment of the U.S. Constitution protects citizens against unreasonable searches and seizures, requiring warrants based on probable cause. As surveillance technologies advance, legal and ethical debates arise over how these tools intersect with Fourth Amendment protections, raising questions about privacy rights and government overreach in the digital age.
