Search and Seizure: Meaning, Differences, Rights, Amendments, Examples & Legal Sections

According to the Bureau of Justice Statistics (BJS), roughly 45 million police–citizen interactions take place in the United States annually, with nearly 4% involving searches, seizures, or both. These interactions form the heart of criminal investigations, yet they remain widely misunderstood by citizens.

What Is a Search?

A search refers to any official action where law enforcement tries to uncover evidence by inspecting a person, home, car, electronic device, or property. A search occurs when police invade a reasonable expectation of privacy.

Examples of searches

There are 7 common examples, including:

1. Opening a car trunk during a traffic stop.
2. Entering a home to look for evidence.
3. Checking pockets during a stop-and-frisk.
4. Scanning a phone’s messages.
5. Using thermal imaging to detect heat sources inside a home.
6. Searching email or cloud storage.
7. Running a drug-sniffing dog inside a building.

What Is a Seizure?

A seizure occurs when the government takes control of a person or property.

There are two main types:

1. Seizure of a Person

This happens when an officer restricts a person’s movement through force, authority, or command.

Examples (5 examples):

• An officer detaining a driver during a traffic stop.
• Placing handcuffs on a suspect.
• Ordering someone to sit on the curb during questioning.
• Blocking someone’s path with police vehicles.
• Arresting a person after probable cause exists.

2. Seizure of Property

This is when officers take possession of items such as:

• Vehicles
• Phones
• Bags
• Money
• Guns
• Drugs
• Computers
• Hard drives

Property seizures must connect to suspected criminal activity.

Difference Between Search and Seizure

The Constitutional Backbone: Fourth Amendment

The Fourth Amendment protects citizens from unreasonable searches and seizures.

Fourth Amendment Text

“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…”

Key Protections

The Fourth Amendment offers 4 major protections:

1. Right to privacy in homes, papers, and personal effects.
2. Protection against unreasonable searches.
3. Protection against unreasonable seizures.
4. Requirement of probable cause for a warrant.

What makes a search “unreasonable”?

Courts ask 2 questions:

1. Did the person have a reasonable expectation of privacy?
2. Did law enforcement violate that expectation without proper justification?

Important Related Amendments

Search and seizure issues often overlap with three additional amendments:

1. Fifth Amendment

Protects against self-incrimination.
Example: Police cannot force someone to unlock a phone with a passcode.

2. Sixth Amendment

Guarantees the right to counsel.
Example: If police seize someone and begin questioning, the person may request an attorney.

3. Fourteenth Amendment

Applies search-and-seizure protections to the states.

When Can Police Seize Property?

Seizure of property occurs under 4 main circumstances:

1. During arrest
2. With a warrant
3. In plain view
4. When property is evidence or contraband

Probable Cause

Probable cause means a reasonable belief based on facts. Examples of probable cause

There are 5 major examples:

1. Witness statements pointing to a suspect
2. Surveillance video showing a person committing an act
3. Smell of drugs in a car
4. Visible weapon during a stop
5. Confession from a suspect

Reasonable Suspicion Explained

Reasonable suspicion is a lower standard than probable cause.

Examples include:

• A person repeatedly pacing outside a closed store
• Visible bulge resembling a weapon
• Running from officers in a high-crime area
• Matching the description of a suspect nearby

The system works when both citizens and law enforcement act within the constitutional boundaries defined by decades of legislation, case law, and procedural safeguards.
