M5: Warrants and Searches of the Home

General Rule: A search of a private residence typically requires a warrant that has been signed by a judge.
Exceptions to the Warrant Requirement:
- Hot Pursuit: Police are chasing a suspect who enters a house.
- Emergencies: Other similar urgent circumstances that justify dispensing with a warrant.
Purpose of Warrants: They serve as a protection against impulsive searches by requiring a neutral master (judge or magistrate) to sign off on a determination of probable cause.
Constitutional Status: Warrants are regarded as the most significant protection provided under the Fourth Amendment.

Magistrate Oversight: Warrant applications are frequently "rubber stamped" rather than critically reviewed.
- A study across seven jurisdictions found that magistrates spent an average of no more than $3\,\text{minutes}$ perusing a warrant application.
Lack of Adversarial Procedure: The application process is "ex parte," meaning it occurs outside the presence of the defense.
- Unlike preliminary hearings or trials, there is no adversarial check at the warrant stage to challenge the police assertions.

Source of Information: Most warrant applications are based on facts provided by confidential informants (CIs) rather than the direct observations of police officers.
Reliability Issues: CIs are often involved in criminal activity themselves and have been known to be "wildly inaccurate."
Motivations for CI Inaccuracy:
- Seeking favorable treatment from law enforcement.
- Desire for monetary gain from search proceeds.
- Seeking revenge against criminal competitors.
Case Studies of CI Failures:
- An informant with a substance abuse disorder once falsely implicated over $50$ individuals.
- The United States Postal Service used $5$ informants who framed over $60$ innocent people.
Manufactured Informants: Police have been known to create fictional informants to justify warrants.
- Boston Example: An officer relied on an informant named "John" for hundreds of warrants. No other officer ever met John, and three other officers eventually repudiated his existence; the government could never produce him.
- Illegal Entry Cover-ups: Officers may illegally enter a home first, find evidence, and then invent an informant to secure a warrant after the fact.
Proposed Solutions and Barriers:
- One solution is to require CIs to be present for questioning by the magistrate.
- The seven-jurisdiction study revealed that police would often rather lose a case than reveal a CI's identity, making this solution impractical.

Constitutional Standard: The Fourth Amendment mandates that a warrant must "particularly describe the place to be searched and the persons or things to be seized."
Primary Goals:
- To prevent house-to-house searches.
- To inhibit the "general ransacking" of a home's interior.
Practical Challenges: While warrants usually prevent house-to-house searches, preventing internal ransacking is difficult.
- If listed items are small, police can search almost everywhere in the house.
Boilerplate Language: A San Diego study found that nearly all warrants used standard language permitting the seizure of "all papers, documents, effects which tend to show possession, dominion, and control over said premises, including fingerprints, handwritings, clothing, and objects bearing a form of identification such as a person's name, photograph, Social Security number, or driver's license number."
- This allows police to search every "nook and cranny" of a residence, as such items could be anywhere.

Seizure of Non-Listed Items: Police may seize evidence not listed in a warrant if it is in "plain view" from a location where they have a legal right to be.
- Example: If police are searching for a large item (like a rifle) and see a pile of cocaine on a coffee table, they may seize the drugs immediately.
Rationale: This prevents drug owners from disposing of contraband while police wait for a second warrant.

Admissibility Rule: Even if an appellate court later determines a warrant lacked probable cause or particularity, evidence remains admissible if a "reasonable officer" could have believed the warrant was valid.
The Exclusionary Rule: This is known as the "good faith exception" to the exclusionary rule (to be discussed further in Module 6).
Effect: This rule effectively dilutes the protections intended by the warrant requirement.

Constitutional Requirement: The Fourth Amendment generally requires police to knock and announce their presence before entering a premises.
The Breonna Taylor Case (Louisville, Kentucky): Taylor was killed by police during a nighttime entry. Her boyfriend fired a weapon thinking the police were intruders; the police returned fire, killing Taylor.
- Controversy: Police claimed they announced themselves; witnesses disputed this.
- Drugs listed in the warrant were not found in the apartment.
Judicial Authorization for No Knock Warrants: The Supreme Court requires an "individualized assessment" by a judge to determine that rapid entry is necessary for officer safety or to prevent the destruction of evidence.
Systemic Issues: Many police departments routinely request no-knock warrants, and many judges routinely grant them without the required individualized assessment.
Enforcement Limitations:
- The Supreme Court has ruled that violations of the "knock and announce" rule do not require the exclusion of evidence found during the search.
- Civil lawsuits (damages remedies) for such violations are rare.
- This makes the requirement extremely difficult to enforce.
