Which Amendment protects against unreasonable searches and seizures?

The Fourth Amendment of the United States Constitution explicitly protects individuals from unreasonable searches and seizures by law enforcement. This protection establishes the requirement for law enforcement to have probable cause and, in many cases, a warrant issued by a neutral judge or magistrate before conducting searches or seizing property. It aims to safeguard citizens' privacy and property rights, ensuring that their personal space is not invaded without just cause.

The other amendments listed do not address the issue of searches and seizures. The Second Amendment pertains to the right to keep and bear arms, the First Amendment covers freedoms of speech, religion, and assembly, and the Fifth Amendment addresses rights related to legal proceedings, such as protection against self-incrimination and double jeopardy. Therefore, the Fourth Amendment is the correct choice as it directly relates to the protection against unreasonable intrusions by government authorities.
