Which amendment of the US Constitution protects a nonpublic area from unreasonable searches and seizures?

The Fourth Amendment of the US Constitution is designed specifically to protect individuals from unreasonable searches and seizures by the government. It establishes the requirement that law enforcement must have a warrant, supported by probable cause, to conduct searches in nonpublic areas, such as homes or private property. This amendment is a fundamental component of the right to privacy in American law and is intended to safeguard citizens against arbitrary interference by state authorities. By requiring that searches be reasonable and legally justified, the Fourth Amendment ensures a balance between individual rights and the needs of law enforcement.
