Summary

The Fourth Amendment guards the citizen’s right to security in person, home, and possessions.
It arose from colonial outrage at general warrants — blank permissions for soldiers to search and seize without cause.
Here, the Framers drew a clear boundary between liberty and authority: the government must justify intrusion before it acts.

This amendment enshrines the principle that suspicion is not enough — evidence, sworn and specific, must guide justice.
It is the shield of the innocent, the restraint upon the state, and the foundation of the American concept of privacy.

Text of the Amendment

The right of the people to be secure in their persons, houses, papers, and effects,
against unreasonable searches and seizures, shall not be violated,
and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation,
and particularly describing the place to be searched, and the persons or things to be seized.

“Amendment IV reminds the Republic that freedom is not the absence of law,
but the presence of limits — that even justice must knock before entering.”
