Execution of a Search Warrant - Comprehensive Notes (Study Guide)

Probable Cause

• Central concept in Fourth Amendment jurisprudence; often considered more fundamental than the warrant requirement. Warrantless searches usually must be based on probable cause, though in some circumstances, reasonable suspicion may justify certain searches (e.g., auto stops, school searches, border searches, pat-downs).
• Defining probable cause is difficult; historically framed as a practical, not technical, standard.
  • 1925 Supreme Court: probable cause exists when the facts known to the police "are sufficient in themselves to warrant a man of reasonable caution in the belief" that an offense has been committed. $ext{Probable cause exists when the facts known to the police are sufficient in themselves to warrant a man of reasonable caution in the belief that an offense has been committed.}$
  • 1949: Court stressed probabilities rather than technicalities, linking probable cause to ordinary, practical considerations of everyday life on which reasonable and prudent people act.
• For search warrants, magistrate has probable cause when there is a reasonable likelihood that a search of a place or seizure of a thing will produce evidence of criminal wrongdoing.
• Illinois v. Gates (1983): "substantial chance" or "fair probability" of criminal activity can suffice for probable cause. $ext{A substantial chance or fair probability of criminal activity suffices for probable cause.}$
• Truthful showing requirement (Franks v. Delaware, 1978): Fourth Amendment demands a factual showing sufficient to comprise probable cause; affiant’s submitted information need not be perfectly accurate, and may be based on hearsay or informants, or information gathered hastily, but it must be believed or appropriately accepted as true by the affiant. $\text{Probable cause may be founded upon hearsay and information from informants, as well as information within the affiant's own knowledge, provided that it is believed or appropriately accepted as true.}$
• Key takeaway: probable cause requires a reasonable likelihood or fair probability, grounded in truthful information, that evidence of crime will be found in the place searched or on the person/place described.

The Particularity Requirement

• Fourth Amendment: warrants must be "particularly describ[ing] the place to be searched and the persons or things to be seized."
• Purpose: limit the search to areas and items for which there is probable cause, ensuring a carefully tailored search and preventing broad, exploratory searches.
• The listing of items to be seized in an application does not suffice if the warrant itself does not contain that list.
• Stanford v. Texas (1965): invalidated a search where the warrant authorized seizure of a broad, unspecified set of items (e.g., books, records, pamphlets, cards, receipts, etc.) and led to an indiscriminate sweep; court called the sweep "constitutionally intolerable" and rejected the general-warrant approach. Justice Stewart emphasized that the Fourth and Fourteenth Amendments guarantee against such general rummaging.
• Ybarra v. Illinois (1979): even with a warrant to search a business (a bar in that case), the warrant does not authorize pat-downs of individuals inside the business who are not linked to the activity described in the warrant. Details on pat-downs will be discussed in chapter 10.

The Knock and Announce Rule and Hudson v. Michigan

• Knock-and-announce rule: generally, officers must knock and announce their presence before entering a dwelling during a warrant execution.
• Hudson v. Michigan (2006): failure to knock and announce does not automatically render evidence seized inadmissible; it shifts the knock-and-announce rule toward an advisory principle rather than a strict exclusionary consequence.
• Implications: while some jurisdictions require knock-and-announce, the Hudson decision reduces the automatic exclusion risk; enforcement may rely on agency policies and state law.
• State variations and bans on no-knock warrants exist:
  • As of 2022, Oregon, Virginia, and Tennessee explicitly ban no-knock warrants.
  • Florida banned no-knock warrants via a 1994 state supreme court decision.
  • Utah prohibits no-knock warrants for drug searches; Maine and Kentucky restrict no-knock warrants to cases with known violent offenders or where officer safety risks exist; time limits may prohibit late-night raids in Kentucky.
  • Thirteen states explicitly allow no-knock warrants.
  • Overall, there remains a patchwork of laws governing no-knock practices across states.

Flash-Bang Grenades: Use in Warrants

• Common in raids led by SWAT teams; flash-bang grenades deliver a brief, intense blast of light and sound to temporarily disorient occupants.
• Historical and contemporary usage:
  • 2015 report noted at least 50 Americans injured, maimed, or killed by flashbangs since 2000 (including injuries during training).
  • In one major city, 84% of raids over a three-year period involved flash-bangs; the department defended this by noting high warrant-service volumes without gunfire.
• No Supreme Court precedent specifically on flash-bangs; federal circuit courts have issued varied decisions depending on facts.

May 2014: Tragic Georgia Case (Flash-Bang Incident)

• SWAT raid on a family's home at 2 a.m.; a flash-bang grenade landed in a crib injuring a 19-month-old child with severe burns.
• The warrant was based on testimony from a roommate of a confidential informant; the deputy claimed to have obtained information via a lieutenant from a U.S. postal inspector, but DOJ later charged that the information was not directly received from a postal inspector and the deputy admitted the wording was misleading.
• Outcomes:
  • The sheriff's deputy who requested the warrant was later found not guilty of the criminal charges.
  • Civil suits resulted in settlements totaling $3.6 million for the family.
• Aftermath: sparked DOJ and media scrutiny regarding the reliability of informants and no-notice risks in raids.

Key Eighth Circuit Decision on Flash-Bang Grenades (2019)

• Kansas City SWAT raid used a flash-bang grenade near a two-year-old; court found the use unreasonable given the suspect had only personal-use quantities of drugs and did not pose a threat to officers.
• The opinion weighed the dangers: flash-bangs are extremely loud and bright, with the potential to damage property, cause burns, or be lethal.
• Acknowledged that flash-bangs can be appropriate when the suspect is known to be armed and dangerous or when surprise is necessary to protect safety.
• Cautioned that the use is less reasonable if innocent bystanders may be present and not identified.

Second Circuit Decision on Flash-Bang Grenades (2014): Terebesi v. Torreso

• Held that a raid involving flash-bang grenades was unreasonable where the suspect had only personal-use quantities of drugs and did not pose a threat.
• Important principle: planners of a raid (not only the executing team) may face §1983 liability if the raid plan results in unconstitutionally excessive force.
• Emphasized accountability for those who formulate and approve raid plans that lead to excessive force.

Detaining a Nearby Person During a Search

• Detention can occur during a search based on a warrant.
• Michigan v. Summers (1981): two primary justifications for detaining on the scene:
  • Prevent flight in the event incriminating evidence is found.
  • Minimize risk of harm to officers.
• Bailey v. United States (2013): if the detained individual is not in the immediate area of the search (e.g., in a car more than a mile away), detention authority is limited and must be justified by other rationale.
• Principle: detentions are reasonable because of the limited intrusion relative to the law-enforcement interests at stake, but constraints apply when individuals are outside the search area.

Use of Force in the Execution of a Warrant

• Reasonable use of force is implicit in detaining individuals pursuant to a search warrant.
• Muehler v. Mena (2005): Summers’ rationale for minimizing risk through controlled command persists; officers should maintain control to minimize harm.
• Graham v. Connor (1989): use of force must be evaluated using an "objective reasonableness" standard; the assessment should be from the perspective of a reasonable officer on the scene, not with the benefit of hindsight.
• The analysis must account for the split-second judgments made in tense, uncertain, rapidly evolving circumstances about the amount of force needed.
• Implication: the level of force is evaluated for reasonableness relative to the situation when used.

Jurisprudence: Notable Decisions on Excessive Force and Raids

• Estate of Redd v. Love, 848 F.3d 899 (10th Cir. 2017)

  • Facts: FBI and BLM executed search and arrest warrants related to theft and trafficking of Native American artifacts; 22 agents involved in the raid; the Redds were arrested without incident; one Redd later committed suicide after bail; the estate sued for excessive force.
  • Holding: no constitutional violation found in this specific case; the court applied Graham v. Connor and a totality-of-the-circumstances approach.
  • Signals potential for excessive-force concerns: large numbers of agents can be viewed as excessive under certain circumstances, but the court did not categorically rule that many agents always constitute excessive force.
  • Factors noted that supported the large force in that case included distrust of the government by residents, perceived hostility from residents’ family members, the decision to search through a large number of artifacts (800+), and prior incidents involving the defendants.
  • Open question: if similar factors are absent in other cases, an excessive number of officers could indicate excessive force, though no federal court had ruled this as a universal rule in 2017.

• Implications across cases:

  • The reasonableness of force and the appropriate number of officers depend on the specific facts, including the threat level, presence of bystanders, and potential for violence.
  • Courts apply a totality-of-the-circumstances approach to assess whether the force used was reasonable under the Fourth Amendment.
  • Procedural and evidentiary concerns (e.g., truthful information in affidavits, no-knock vs. knock-and-announce, and planning of raid) are central to assessing constitutional compliance in warrant executions.

• Real-world relevance and ethical considerations:

  • Debates over no-knock warrants and the use of flash-bangs reflect tensions between officer safety and civilian harm.
  • High-profile incidents (e.g., Breonna Taylor case) prompted policy reforms, including bans or restrictions on no-knock warrants and modifications to raid practices in several jurisdictions and federal agencies.
  • The balance between effective law enforcement and protecting individual rights remains a central theme in constitutional law regarding warrants and searches.

Breonna Taylor Case (Summary and Implications)

• Overview: A 26-year-old Black woman killed during a botched raid in Louisville, Kentucky, on March 23, 2020.
• Warrant: Entered Taylor's apartment under a search warrant; investigation focused on two men at a different property; affidavit claimed verification through a U.S. Postal Inspector that a suspect was receiving packages, which later proved to be misleading or not directly verified.
• Raid circumstances: Knocking and announcing were contested; a neighbor reported uncertainty about whether officers identified themselves; the door was forced open; a boyfriend fired after fearing a break-in; multiple officers fired back.
• Outcomes:
  • No drugs found in Taylor's apartment; no charges against Taylor’s boyfriend related to drug activity.
  • Several officers were disciplined or fired for actions during the raid or in the warrant process.
  • The case intensified public debate about no-knock raids, warrant accuracy, and officer accountability.
• Reforms and policy responses:
  • Louisville banned no-knock raids in June 2020 and Kentucky enacted legislation restricting no-knock warrants in April 2021.
  • Some cities (e.g., Memphis, Indianapolis) implemented cap or reform measures.
  • August 2021: U.S. Department of Justice announced limits on no-knock warrants by FBI, DEA, and U.S. Marshals, reserving them for situations where it is necessary to avoid death or serious injury.
• Connection to the broader material:
  • Illustrates the practical consequences of warrant practices and the ethical implications of raid tactics.
  • Demonstrates how legislative and departmental reforms can emerge in response to high-profile incidents and public scrutiny.

Connections to Foundational Principles and Real-World Relevance

• Probable cause links to reasonable expectations of evidence gathering and the belief that a crime has been or will be committed.
• Particularity ensures searches are tailored to specific evidence, limiting invasions of privacy and preventing general rummaging.
• Knock-and-announce rules reflect a balance between the government’s interest in enforcing the law and the privacy and safety rights of residents.
• The use of force and the number of officers during raids are evaluated by objective reasonableness, requiring courts to balance officer safety and community impact against individual rights.
• The evolving jurisprudence and reform efforts (e.g., Breonna Taylor aftermath) demonstrate the dynamic nature of constitutional law, where policy changes, case law, and practice converge to shape law enforcement procedures.

Key Takeaways for Exam Preparation

• Be able to define probable cause and explain its evolving standards (1925 definition; Gates standard of substantial chance/fair probability; Franks’ truthfulness concept).
• Understand the purpose and limits of the particularity requirement, with notable contrast in Stanford v. Texas and Ybarra v. Illinois.
• Explain the knock-and-announce rule, its Hudson v. Michigan effect, and the practical implications for raid planning and policy variation across states.
• Recognize the role of flash-bang grenades in raids, including their risks, the circuit-specific outcomes, and the planning implications highlighted by Terebesi v. Torreso and related cases.
• Know the justifications for detaining individuals during a search ( Summers ) and the limits when the person is not in the immediate area of the search ( Bailey ).
• Articulate the objective reasonableness standard for use of force ( Graham ) and how courts assess force in the context of warrant execution ( Muehler; similar principles in other cases ).
• Appreciate the real-world impact of raid practices on civil rights, with Breonna Taylor as a central case study for policy reform and accountability.
• Be prepared to cite representative numbers and examples from the material (e.g., % of raids with flash-bangs, injuries, or deaths, and specific factual details in notable cases) using proper LaTeX formatting where numerical data or formulas appear.

Appendix: Notable Numerical References (for quick review)

• 80% of 800 raids involved execution of search warrants (ACLU study, 2011–2012); drugs implicated in ~60% of these raids; disproportionately in communities of color. $80 ext{\% of }800=0.8\times800=640\text{ raids involved execution of search warrants, with ~60\% drug-related.}$
• From 2010–2016, police raids resulted in 94 deaths, including 13 officers (New York Times reporting).
• Flash-bangs in some cities used in 84\% of raids over a 3-year period in one city. $0.84\approx 84\%.$
• Flash-bang device characteristics cited in Eighth Circuit decision: light intensity ~107 times brighter than high-beam headlights; temperature around $5{,}000^{\circ}\text{F}$; audible output far exceeding a typical shotgun blast.
• Breonna Taylor case: no drugs found; no charges against the principal residents involved; policy reforms followed at local/state/federal levels.
