What article of the constitution protects nonpublic areas from unreasonable search and seizures?

The Fourth Amendment of the United States Constitution, which falls under Article 4, explicitly protects individuals from unreasonable searches and seizures. This amendment establishes a fundamental right to privacy, particularly in areas where individuals have a reasonable expectation of privacy, such as homes, personal belongings, and other nonpublic spaces. It requires law enforcement to obtain a warrant based on probable cause before conducting searches or seizures in these areas, thereby providing a critical safeguard against government overreach and ensuring that individuals' privacy rights are respected. This constitutional protection underscores the importance of maintaining personal liberties in both public and private realms.
