Which amendment in the U.S. Constitution protects against unreasonable searches and seizures?

The amendment that protects against unreasonable searches and seizures is the Fourth Amendment. This amendment is a crucial component of the Bill of Rights and is designed to safeguard individuals' privacy and security against arbitrary governmental actions. It requires law enforcement to have probable cause and, in most cases, to obtain a warrant issued by a judge before conducting searches or seizing property.

This protection is vital in ensuring that individuals have a right to their personal belongings and privacy, limiting the power of the state and its law enforcement agencies. Additionally, the Fourth Amendment establishes guidelines to help courts evaluate whether a search or seizure has been conducted legally. By specifically addressing the necessity of warrants and probable cause, the Fourth Amendment plays a fundamental role in upholding citizens' rights in a democratic society.
