Which amendment relates to the protection against unreasonable searches and seizures?

The Fourth Amendment is pivotal in protecting individuals from unreasonable searches and seizures by the government. It establishes that citizens have the right to be secure in their persons, houses, papers, and effects against such intrusions. This amendment mandates that law enforcement authorities must generally obtain a warrant, supported by probable cause, before conducting searches or making arrests. This legal framework is essential to safeguarding privacy and upholding civil liberties, forming a critical part of the broader Bill of Rights.

The other amendments mentioned focus on different aspects of rights and protections. The Sixth Amendment pertains to the rights of criminal defendants, including the right to a speedy trial and legal counsel. The Fourteenth Amendment primarily addresses citizenship rights and equal protection under the law, while the First Amendment protects freedoms concerning religion, expression, assembly, and the press. Each of these amendments plays a significant role in defining individual rights but does not specifically address the issue of searches and seizures.
