The 4th Amendment safeguards individuals from unreasonable searches and seizures, ensuring that warrants must be judicially sanctioned and supported by probable cause. It plays a crucial role in limiting government power and protecting privacy in personal spaces. Originating as a response to British abuses, its interpretation has evolved through landmark cases like Katz v. United States and Mapp v. Ohio, which expanded protections against illegal evidence in court. Smith v. Maryland further illustrates the complexities of privacy rights under this amendment.
