The freedom from unreasonable search and seizure is one among many rights that protects citizens from government overreach. This lesson discusses the definition, background, and application of the amendment that protects this right.

The Fourth Amendment

Can a government official enter your home, search your closet, and take your most prized possessions, even though you've done nothing wrong? If you're pulled over, can a cop open your trunk and search all of your belongings for no reason whatsoever and without your consent? No! Government officials and law enforcement cannot invade our privacy and take whatever they want, unless there is a warrant or strong suspicion we are involved in questionable activities. So, we know that we, as citizens of the United States, have freedom from unreasonable search and seizure.

But where does this right come from? If you guessed the Constitution, you're right! The Fourth Amendment to the Constitution protects citizens from governmental abuse of power, or, more specifically, from baseless warrants and unreasonable searches and seizures.

What Does the Fourth Amendment Actually Say?

The Fourth Amendment reads: '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.'

There are in fact two main rights laid out in the Fourth Amendment. The first part of the amendment protects citizens from searches and seizures that are specifically unreasonable in nature. The second part of the amendment dictates that warrants should state exactly who and what they are for, and warrants will only be issued if there is probable cause (or a good reason). On a basic level, that means that law enforcement and the government cannot search or seize an individual's private property for no reason whatsoever. Reasonable searches and seizures are legal as long as a specific process is followed (probable cause exists and a warrant is issued, but on rare occasions, extreme situations may justify an immediate search without a warrant, such as when there is a dangerous person at-large and people are in danger).

What Is the Background of the Fourth Amendment?

The Fourth Amendment was passed as part of the Bill of Rights, a name given to the first 10 amendments to the Constitution. The Bill of Rights enumerates some of the many rights that all citizens of the United States are guaranteed. The Bill of Rights was fully ratified in 1791.

The creators of the Constitution wanted to protect the rights of American citizens.

The Fourth Amendment rose out of several bad experiences with the British government. Before the American Revolution, the British government had been violating the American colonists' rights for quite some time. For example, the British would issue writs of assistance, which were broad search warrants that allowed government officials to search basically anyone and anything, even without a good reason. They were used to enforce laws, but the colonists saw them as a major abuse of power.

So, when it came time to form their own government, the men who created the Constitution wanted to prevent the kind of abuse that had come from the writs of assistance. The Fourth Amendment was the authors' guarantee to the people that the government would be limited in what it can search and seize from private citizens.

How Has the Fourth Amendment Been Applied?

The Fourth Amendment sounds simple enough, but courts have had a hard time interpreting it. The Fourth Amendment (combined with the Fourteenth Amendment) gives Americans a right to some degree of privacy, even though a 'right to privacy' is not explicitly stated anywhere in the Constitution. The Fourth Amendment tries to strike a balance between protecting the individual against government overreach while still enabling the government to find and punish criminal activity.
