Under which amendment is the government prohibited from conducting searches without a warrant?

The 4th Amendment to the United States Constitution is vital in protecting individuals from unreasonable searches and seizures by the government. It establishes that law enforcement must obtain a warrant, supported by probable cause, before conducting most searches. This requirement is fundamental in upholding citizens' privacy and property rights, ensuring that individuals are protected from arbitrary governmental interference.

The other amendments mentioned have distinct purposes. The 3rd Amendment addresses the quartering of soldiers in private homes without consent, while the 5th Amendment relates to rights in criminal proceedings, including protection against self-incrimination and double jeopardy. The 6th Amendment guarantees the rights of defendants in criminal prosecutions, including the right to a speedy trial and legal counsel. Although each of these amendments plays a crucial role in the American legal framework, it is the 4th Amendment that specifically deals with the necessity of a warrant for searches conducted by government officials.
