Which amendment protects against unreasonable searches and seizures?

The Fourth Amendment is pivotal in protecting individuals' rights against unreasonable searches and seizures. It establishes that law enforcement must have probable cause, and typically, they must obtain a warrant based on that cause before searching a person's property or seizing their possessions. This amendment was crafted to address the colonists' grievances regarding arbitrary searches by British authorities, ensuring that citizens have a reasonable expectation of privacy.

In contemporary law enforcement practices, the Fourth Amendment serves as a fundamental safeguard against abuse of power, requiring law enforcement to justify their actions when intruding on a person's privacy. It plays a critical role in maintaining the balance between community safety and individual liberties, ensuring that actions taken by law enforcement are reasonable and legally justified.
