Week 2 Part 2 | Arrests & Searches Incident to Arrest

Fourth Amendment – Seizures and Arrests 

 
 

I. Overview of Seizures 

  • Fourth Amendment protects against unreasonable searches and seizures. 

  • Two types of seizures: 

    1. Seizures of things 

    2. Seizures of people 

 
 

II. Seizure of Things 

  • Occurs when the government exercises control over property. 

  • Common examples: 

    • Taking drugs found during a search 

    • Seizing weapons or contraband 

    • Freezing or controlling financial assets 

  • Requirements: 

    • Typically require a warrant based on probable cause. 

    • Must be executed lawfully. 

 
 

III. Seizure of People 

  • A person is seized when: 

    • They are not free to leave or end the interaction with police. 

  • Includes: 

    • Arrests 

    • Detentions 

    • Use of force (e.g., shooting by police) 

 
 

IV. Arrest as a Seizure 

  • Arrest is the clearest form of seizure of a person. 

  • Must be reasonable to comply with the Fourth Amendment. 

 
 

V. Requirements for a Lawful Arrest 

Two primary requirements: 

  1. Probable Cause 

    • Must show: 

      • A crime has been committed 

      • The person arrested committed the crime 

  2. Warrant Requirement (depends on location) 

    • Public vs. home determines whether a warrant is required 

 
 

VI. Probable Cause for Arrest 

  • Requires: 

    • Connection between the suspect and the crime 

  • Not enough: 

    • To show only that a crime occurred 

  • Must also show: 

    • The specific individual likely committed it 

 
 

Example: Maryland v. Pringle 

  • Drugs found in a car with multiple occupants. 

  • All individuals arrested. 

  • Issue: 

    • Whether probable cause existed for each person. 

  • Key lesson: 

    • Must tie evidence to the specific person being arrested. 

 
 

VII. Arrests in Public – United States v. Watson 

  • Rule: 

    • No arrest warrant required in public. 

  • Requirement: 

    • Only probable cause is needed. 

  • Applies to: 

    • Felonies 

    • Misdemeanors and traffic offenses (extended doctrine) 

 
 

Court’s Reasoning 

  • Supported by: 

    • Historical common law practices 

    • Congressional authorization of warrantless arrests 

  • Emphasis: 

    • Longstanding acceptance of this rule in U.S. law 

 
 

VIII. Arrests in the Home – Payton v. New York 

  • Rule: 

    • Arrest warrant is required to enter a home and arrest someone. 

  • Requirements: 

    • Probable cause 

    • Arrest warrant (unless exception applies) 

 
 

Court’s Reasoning 

  • Home receives highest level of privacy protection. 

  • Entering a home to arrest is: 

    • Equivalent in intrusiveness to a search 

  • Therefore: 

    • Same level of constitutional protection applies 

 
 

IX. Key Distinction: Public vs. Home Arrests 

Location 

Requirements 

Public 

Probable cause only 

Home 

Probable cause + arrest warrant 

 
 

X. Exceptions to Warrant Requirement 

  • Even in homes, warrant may not be required if: 

    • Exigent circumstances exist (e.g., emergencies) 

    • Consent is given 

  • These exceptions are limited and fact-specific. 

 
 

XI. Tension in Doctrine 

  • Different standards for: 

    • Searches (generally require warrants) 

    • Arrests in public (do not require warrants) 

  • Criticism: 

    • Arrest may be more intrusive than search 

  • Court’s response: 

    • Relies on history and tradition over strict logical consistency 

 
 

XII. Key Takeaways 

  • Arrests are seizures governed by the Fourth Amendment. 

  • Must be: 

    • Based on probable cause 

  • Warrant requirement depends on location: 

    • Public → no warrant required 

    • Home → warrant required 

  • Strong protection for: 

    • Privacy in the home 

  • Analysis always depends on: 

    • Facts and context of the situation 

 

Fourth Amendment – Search Incident to Arrest 

 
 

I. Overview of Exceptions to the Fourth Amendment 

  • General rule: 

    • Searches and seizures require probable cause and a warrant. 

  • However, Supreme Court has created exceptions due to competing interests: 

    • Protecting privacy and liberty 

    • Promoting public safety and crime control 

  • Exceptions vary: 

    • Some eliminate the warrant requirement only 

    • Others eliminate both warrant and probable cause requirements 

 
 

II. Search Incident to Arrest Exception 

  • One of the most important exceptions. 

  • When it applies: 

    • Police do not need a warrant 

    • Police do not need additional probable cause for the search 

  • Requirement: 

    • There must first be a lawful arrest 

 
 

III. Chimel v. California 

A. Key Holding 

  • Search incident to arrest is limited in scope. 

  • Police may search: 

    1. The arrestee’s person 

    2. The area within the arrestee’s immediate control 

 
 

B. Policy Justifications 

  1. Officer safety 

    • Prevent access to weapons. 

  2. Preservation of evidence 

    • Prevent concealment or destruction.  

 
 

C. Scope of Permissible Search 

  • Allowed: 

    • Items on the arrestee’s body 

    • Areas within grabbing distance (wingspan) 

    • Nearby containers or surfaces within reach 

    • Not allowed: 

      • Entire house search 

      • Areas beyond immediate control 

      • Remote rooms or distant containers 

 
 

D. Additional Allowances 

  • Police may: 

    • Search closets or immediately adjoining spaces where an attack could occur 

  • Protective sweep: 

    • Limited inspection of home allowed only if: 

      • Reasonable suspicion someone dangerous is present 

 
 

IV. United States v. Robinson 

A. Key Rule 

  • Bright-line rule: 

    • A lawful custodial arrest automatically allows a search of the person 

  • No additional justification required: 

    • No need to show officer feared weapons or evidence destruction 

 
 

B. Scope 

  • Police may search: 

    • Clothing 

    • Body 

    • Containers on the person (e.g., cigarette packs, bags) 

 
 

C. Key Principle 

  • The fact of the arrest alone justifies the search. 

 
 

D. Criticism 

  • Dissent argues: 

    • Too intrusive to allow inspection of all containers 

    • Suggests waiting for a warrant after securing items 

 
 

V. Requirement of a Lawful Arrest 

  • Search incident to arrest only valid if: 

    • The arrest itself is lawful 

  • If arrest is invalid: 

    • The search is also invalid 

 
 

VI. Citation vs. Arrest – Knowles v. Iowa 

  • If officer issues a citation instead of arrest: 

    • No search incident to arrest allowed 

  • However: 

    • Officers can choose to make an arrest → enables search 

  • Even if state law prefers citations: 

    • Federal constitution still allows search if arrest occurs 

 
 

VII. Racial Disparities 

  • Application of arrest discretion may lead to: 

    • Unequal enforcement 

    • Disproportionate searches of certain groups 

  • Practical impact: 

    • Increased exposure to searches for some populations 

 
 

VIII. Vale v. Louisiana 

A. Key Rule 

  • Arrest location limits scope of search: 

    • If arrested outside the home: 

      • Cannot search inside the home under this exception 

 
 

B. Holding 

  • Search must be: 

    • Contemporaneous with arrest 

    • Limited to immediate vicinity 

 
 

IX. Timing of Search and Arrest 

  • General rule: 

    • Arrest occurs before search 

  • Exception: 

    • Search can occur first if: 

      • Arrest follows immediately 

      • Probable cause existed beforehand 

 
 

X. Key Principles 

  1. Lawful arrest is required. 

  2. No warrant or additional probable cause needed for the search. 

  3. Search must be limited to: 

    • Person 

    • Immediate control area 

  4. Scope depends on: 

    • Location of arrest 

    • Proximity to searched area 

  5. Exception is justified by: 

    • Safety and evidence concerns 

 
 

XI. Key Takeaways 

  • Search incident to arrest is a major exception to Fourth Amendment protections. 

  • It allows: 

    • Automatic search of person and nearby areas upon lawful arrest. 

  • Courts impose limits: 

    • Must stay within immediate control zone. 

  • Bright-line rules (Robinson) reduce need for case-by-case analysis. 

  • Doctrine reflects balance between: 

    • Individual liberty 

    • Law enforcement needs
