2.4 Search, Seizure & Exclusionary Rule

Search, Seizure & Exclusionary Rule

Introduction

The 4th Amendment protects against unreasonable searches and seizures. The foundational principle is that a search conducted without a warrant is per se unreasonable, subject only to a few specifically established and well-delineated exceptions. Law enforcement officers must understand both the requirements for obtaining a valid search warrant and the specific circumstances where a warrant is not required.

Search Warrant Requirements

A search warrant is an order in writing, signed by a judge, directed to a peace officer, commanding the officer to search for personal property and bring it before the judge. To be valid, a search warrant must meet strict constitutional and statutory requirements:

1. Probable Cause: The officer must provide sufficient facts to lead a reasonable person to believe that evidence of a crime is located in the place to be searched.
2. Affidavit: The probable cause must be sworn to in a written affidavit submitted to the judge.
3. Particularity: The warrant must particularly describe the place to be searched and the persons or things to be seized. General, open-ended warrants are unconstitutional.
4. Neutral and Detached Magistrate: The warrant must be reviewed and signed by a judge who is independent of law enforcement.

Execution Scope: Officers may only search in areas where the items listed in the warrant could reasonably be hidden. For example, if the warrant is for a stolen 65-inch television, officers cannot search inside small desk drawers. Once all items listed in the warrant are found, the search must conclude.

Exceptions to the Warrant Requirement

Given the dynamic nature of policing, the courts recognize several exceptions where requiring a warrant would be impractical or dangerous.

1. Search Incident to a Lawful Arrest (SITA)

When an officer makes a lawful custodial arrest, they may perform a full search of the arrestee's person and the area within their immediate control (the "wingspan" or "lunge area"). The purposes are to remove weapons that could be used to resist arrest or effect escape and to prevent the destruction of evidence.

• Note on Vehicles: Following Arizona v. Gant, officers can only search the passenger compartment of a vehicle incident to arrest if the arrestee is unsecured and within reaching distance of the compartment at the time of the search, OR if it is reasonable to believe the vehicle contains evidence of the offense of arrest.

2. Plain View Doctrine

Officers may seize evidence without a warrant if:

1. The officer is lawfully present at the location where the evidence can be viewed.
2. The officer has a lawful right of access to the object itself.
3. The incriminating character of the object is "immediately apparent" (probable cause exists without moving or manipulating the item).

3. Consent

A search is valid if a person with authority over the premises or items voluntarily gives consent. The consent must be free from coercion. Officers do not necessarily have to inform the person that they have the right to refuse, but refusal rights factor into the voluntariness analysis.

4. Exigent Circumstances

Warrants are not required when emergencies make getting a warrant impossible or extremely impractical. Common exigencies include:

• Hot pursuit of a fleeing felon.
• Imminent destruction of evidence.
• Emergency aid (to prevent imminent injury or death).

5. Automobile Exception (Carroll Doctrine)

If officers have probable cause to believe a vehicle contains contraband or evidence of a crime, they may search the vehicle without a warrant. The rationale is that vehicles are inherently mobile, and obtaining a warrant might allow the vehicle to be moved and evidence lost. This exception allows a search of the entire vehicle, including the trunk and any containers that could reasonably hold the object of the search.

6. Inventory Searches

When law enforcement lawfully impounds a vehicle, they may conduct an administrative inventory of its contents. This is not for gathering evidence but to protect the owner's property, protect the police against claims of lost property, and protect officers from dangerous items. It must be conducted according to standardized department policy.

The Exclusionary Rule

The Exclusionary Rule is a judicially created remedy designed to deter police misconduct. It states that evidence obtained by law enforcement officers in violation of the 4th Amendment cannot be used against the defendant in a criminal trial.

• Origin: Established federally in Weeks v. United States and applied to the states in Mapp v. Ohio (1961).

Fruit of the Poisonous Tree Doctrine

An extension of the Exclusionary Rule. If the initial search or seizure is illegal (the "poisonous tree"), any secondary evidence discovered as a result of that illegality (the "fruit") is also inadmissible. For example, if officers conduct an illegal search and find a map leading to stolen goods, both the map and the stolen goods are suppressed.

Good Faith Exception

In United States v. Leon, the Supreme Court established the "Good Faith Exception." If officers act in objectively reasonable, good-faith reliance on a search warrant issued by a detached and neutral magistrate that is later found to be defective, the evidence will not be excluded. The rationale is that excluding the evidence would not deter police misconduct, as the officers were trying to follow the rules by getting a warrant.

Understanding these rules is critical. A perfectly executed investigation can be ruined entirely if a single search violates the 4th Amendment, leading to the suppression of crucial evidence.
