Which amendment protects individuals against unreasonable search and seizure?

The Fourth Amendment is crucial in the context of criminal justice and individual rights as it specifically addresses the protection of citizens from unreasonable searches and seizures by the government. This amendment establishes that law enforcement must have probable cause and, in most situations, a warrant issued by a judge before conducting searches of private property or seizing personal belongings. This protection is foundational in ensuring that individuals have a reasonable expectation of privacy in their homes and personal effects, which is essential in upholding civil liberties and preventing arbitrary government interference.

Other amendments mentioned, while they cover important rights, do not specifically relate to the issue of searches and seizures. The First Amendment focuses on freedom of speech, religion, and assembly; the Fifth Amendment provides rights related to self-incrimination and due process; and the Sixth Amendment guarantees the right to a fair trial. Each of these plays a significant role in the justice system, but the Fourth Amendment is the one directly concerned with protecting against unreasonable search and seizure practices.
