- Which aspect of the police conduct was most clearly a violation of the Fourth Amendment? Select one.
Answer: Searching the upstairs bedrooms, closets, and under beds.
The correct answer is D. Police may conduct a protective sweep of the premises incident to an in-home arrest if they have a reasonable, articulable suspicion that the area to be swept harbors an individual posing a danger. A protective sweep is limited to a cursory visual inspection of those places in which a person might be hiding. Searching inside closets and under beds in upstairs bedrooms, far from the arrest location, likely exceeded the permissible scope of a cursory sweep unless police had specific facts to justify such a broad search, which are not provided. A is incorrect; an arrest warrant carries the limited authority to enter a dwelling in which the suspect lives when there is reason to believe the suspect is within. B is likely permissible as a sweep of an immediately adjoining space without needing reasonable suspicion. C is likely permissible under the plain view doctrine, as the officer was lawfully in the kitchen as part of the sweep when he saw the key. Therefore, the most clear constitutional violation was the broad search of the upstairs rooms.
- Which of the following is your strongest argument for suppressing the evidence found in the bedroom? Select one.
Answer: The roommate lacked actual or apparent authority to consent to a search of your client's private bedroom.
The strongest argument is B. For third-party consent to be valid, the consenting party must have either actual or apparent authority over the area to be searched. While a roommate generally has authority to consent to a search of common areas, they typically lack authority over areas where another resident has an exclusive expectation of privacy, such as a separate bedroom. The police could not reasonably believe the roommate had authority over the client's private bedroom. A is a weaker argument because the test for voluntariness is based on the totality of the circumstances, and mere intimidation is often insufficient to render consent involuntary. C is incorrect; if the client were present and objected, the consent would be invalid (Georgia v. Randolph), but the facts do not state the client was present and objecting. D is a plausible but weaker argument than B; the primary issue is the roommate's authority to consent to searching the bedroom at all, not just the scope within the bedroom.
- The suspect's attorney has filed a motion to suppress the stolen goods found in the home. What is the basis for the strongest argument in support of the motion? Select one.
Answer: The evidence from the home is fruit of the poisonous tree because the GPS tracking was unlawful.
The correct answer is D. This is a multi-step problem. First, under United States v. Jones, attaching a GPS device to a vehicle constitutes a search under the Fourth Amendment, which generally requires a warrant. The detective's warrantless attachment of the device was therefore an unlawful search (Answer A is a correct statement of law). The evidence gathered from this unlawful search (the car's location) was then used to establish probable cause for the search warrant for the home. Under the 'fruit of the poisonous tree' doctrine, evidence derived from an earlier illegality is inadmissible. Therefore, the stolen goods found in the home are tainted by the initial illegal GPS search and should be suppressed. D is the best answer because it connects the initial illegality (the GPS tracking) to the evidence the motion seeks to suppress (the stolen goods). A, B, and C describe the underlying constitutional violation but do not fully address why the evidence from the home search should be suppressed.
- A motion to suppress the cocaine is filed. How should the court rule? Select one.
Answer: Grant the motion, because the officer's seizure of the bag exceeded the scope of a lawful Terry frisk.
The correct answer is B. A Terry frisk, or pat-down, is justified by a reasonable suspicion that the suspect is armed and dangerous. Its scope is limited to a search for weapons. Under the 'plain feel' doctrine, an officer can seize non-weapon contraband if its identity as contraband is 'immediately apparent' during the pat-down. Here, feeling a 'soft, crinkly object' is not sufficient to make its identity as cocaine immediately apparent. The officer had to manipulate it or go beyond the scope of a weapons search to identify it, making the seizure unlawful. A is incorrect because the man's actions upon seeing the officer likely provided reasonable suspicion for an investigatory stop. C is incorrect because the officer did not have probable cause for an arrest until after the illegal search; the search cannot be justified by a subsequent arrest. D is incorrect because, as explained, the nature of the soft bag as contraband was not 'immediately apparent' from the pat-down alone.
- The suspect files a motion to suppress the evidence. What is the suspect's strongest argument for suppression? Select one.
Answer: The triggering condition for the warrant was not met as written.
The correct answer is B. Anticipatory warrants are constitutional, but their execution is permissible only after the specified triggering condition has occurred. The warrant must contain explicit and clear conditions. Here, the condition was delivery 'by a uniformed officer.' Because a plainclothes officer made the delivery, the triggering condition was not strictly met. This failure to comply with the express terms of the warrant is the strongest basis for suppression. A is incorrect because the Supreme Court has upheld the constitutionality of anticipatory warrants. C is an argument about the merits of the case (the suspect's knowledge), not the validity of the warrant itself. D is irrelevant; there is no requirement that the same officers witness the triggering event and execute the warrant.
- The homeowner's attorney moves to suppress the marijuana, arguing it was outside the scope of the warrant. How should the court rule? Select one.
Answer: Deny the motion, because the officers were lawfully searching a place where firearms could be found when they discovered the marijuana in plain view.
The correct answer is C. When executing a search warrant, police may search containers and areas where the items specified in the warrant could plausibly be located. A dresser drawer is a place where firearms could be hidden. Under the plain view doctrine, if police are lawfully in a position to view an item, and its incriminating character is immediately apparent, they may seize it without a warrant. Here, the officers were lawfully executing the warrant when they opened the drawer, and the incriminating nature of marijuana is immediately apparent. Therefore, the seizure was lawful. A is incorrect because the plain view doctrine allows for the seizure of contraband not listed in the warrant. B is incorrect because information about a firearm purchase a week prior is not necessarily stale. D is incorrect as the discovery of items listed in the warrant doesn't retroactively validate the seizure of other items; the seizure of the marijuana must be independently justified, which it is by the plain view doctrine.
- The driver moves to suppress the marijuana. Which argument provides the strongest basis for suppression? Select one.
Answer: The officer's stop of the vehicle constituted an unlawful seizure because he was acting under color of law without justification.
The correct answer is D. For the Fourth Amendment to apply, there must be government action. An officer acting outside the scope of their official duties might be considered a private citizen, but here, by using a police siren and demanding documents, the officer was acting 'under color of law.' This action constituted a seizure (a traffic stop). Since the seizure was based on personal anger over a minor traffic infraction and not on any lawful authority or reasonable suspicion of an ongoing crime, it was an unreasonable seizure in violation of the Fourth Amendment. The marijuana discovered as a result of this unlawful seizure is fruit of the poisonous tree. A is a possible issue but less fundamental than the lack of justification for the stop itself. B is incorrect, as being in uniform is not a constitutional prerequisite for an officer to take action. C is incorrect because the use of the siren demonstrates the officer was invoking his official authority, making him a state actor.
- The woman's attorney has moved to suppress the heroin. What is the probable outcome of the motion? Select one.
Answer: Denied, because the search was a lawful inventory search conducted pursuant to established police procedure.
The correct answer is D. An inventory search is a well-established exception to the warrant requirement. Such searches are permissible to protect the arrestee's property, protect the police from false claims of theft, and ensure facility safety. For an inventory search to be valid, it must be conducted in good faith according to standardized, established police procedures. The facts state the search was part of a 'routine booking procedure' and that a 'written policy' existed, satisfying these requirements. A is incorrect because the justification for an inventory search is administrative, not evidence-gathering related to the crime of arrest. B is incorrect because inventory searches are a specific exception to the warrant requirement. C is incorrect because a search incident to arrest is typically conducted at the time and place of the arrest. While a search of the purse at the scene would have been a valid SILA, the search at the station is better justified as an inventory search.
- The homeowner's attorney has filed a motion to suppress the cocaine. What is the prosecution's strongest argument for the admissibility of the evidence? Select one.
Answer: The officer's entry was justified by the exigent circumstance of preventing the imminent destruction of evidence.
The correct answer is A. While the officer's initial observation was lawful under the plain view doctrine (as he was in a lawful vantage point on the porch), the plain view doctrine alone does not justify a warrantless entry into a home. However, the observation of easily destructible evidence like cocaine can create an exigent circumstance—the risk of imminent destruction—that justifies a warrantless entry to secure the evidence. B is incorrect because plain view allows for seizure without a warrant only if the officer is already lawfully present in the location where the evidence is; it does not authorize a warrantless entry into a home. C is incorrect because a search incident to arrest cannot precede the arrest itself and justify the entry; the arrest had not yet occurred. D is a correct statement regarding the initial observation, but it does not address the legality of the subsequent warrantless entry into the home, which is the key issue for suppression.
- The suspect moves to suppress the cocaine, arguing that the officers' entry into his apartment violated the Fourth Amendment's 'knock and announce' rule. If the court finds that the officers did violate the rule, what is the likely result of the motion to suppress? Select one.
Answer: Denied, because the exclusionary rule does not apply to violations of the knock-and-announce rule.
This question tests your understanding of the knock-and-announce rule and the exclusionary rule's limitations in Fourth Amendment law. When you see a search and seizure question involving procedural violations, always consider whether the remedy fits the violation.
The knock-and-announce rule requires officers to announce their presence and wait a reasonable time before entering, but the Supreme Court in Hudson v. Michigan (2006) held that violating this rule doesn't trigger the exclusionary rule. The Court reasoned that the purpose of knock-and-announce is to protect life, property, and privacy dignity during entry—not to prevent the discovery of evidence. Since the cocaine would have been found regardless of the improper entry timing, suppression isn't the appropriate remedy.
Looking at the wrong answers: Option B incorrectly suggests that officers needed a special "no-knock" warrant, but they had a valid arrest warrant and the issue is remedy, not authorization. Option C reflects the common misconception that all Fourth Amendment violations require suppression—this was true before Hudson but no longer applies to knock-and-announce violations. Option D focuses on whether five seconds was reasonable, but even if the officers did violate the rule (as the question assumes), this doesn't determine the suppression issue.
The correct answer is A because Hudson specifically established that knock-and-announce violations don't justify excluding evidence under the Fourth Amendment.
Study tip: Remember that not every Fourth Amendment violation triggers the exclusionary rule. The Supreme Court has created exceptions where the costs of suppression outweigh the deterrent benefits, with knock-and-announce being a key example.
- The driver was charged with illegal possession of a firearm. His attorney filed a motion to suppress, arguing the initial stop at the checkpoint was an unconstitutional seizure. How is the court most likely to rule on the motion? Select one.
Answer: Deny the motion, because the checkpoint was a reasonable seizure under the special needs doctrine.
The correct answer is C. The Supreme Court has upheld sobriety checkpoints as a reasonable type of seizure under the 'special needs' doctrine, which balances the state's interest (e.g., eradicating drunk driving) against the intrusion on individual liberty. Because the checkpoint was conducted under established guidelines to serve the special need of highway safety and the intrusion was minimal, the stop was constitutional. Once the car was lawfully stopped, the officer could seize the firearm under the plain view doctrine. A is incorrect because sobriety checkpoints are a recognized exception to the requirement of individualized suspicion. B is incorrect because the stated purpose was highway safety (sobriety), not general crime control, which the Supreme Court has found unconstitutional (City of Indianapolis v. Edmond). D is incorrect because the driver was seized (stopped), so he has standing to challenge the legality of that seizure.
- The farmer's attorney moves to suppress the evidence, arguing that the helicopter surveillance constituted a warrantless search that violated the farmer's reasonable expectation of privacy. How is the court most likely to rule? Select one.
Answer: Deny the motion, because the observation was made from a lawful public vantage point where the officer had a right to be.
When you encounter Fourth Amendment questions involving aerial surveillance, focus on the "reasonable expectation of privacy" test and whether law enforcement observed from a lawful vantage point.
A is correct because the Supreme Court has consistently held that observations made from public airspace at lawful altitudes do not constitute searches under the Fourth Amendment. In cases like California v. Ciraolo and Florida v. Riley, the Court established that if police are where they have a legal right to be (here, 500 feet in public airspace), their observations don't violate the Fourth Amendment, even if they can see into private property.
B is wrong because while the field might be part of the curtilage, curtilage protection doesn't extend to aerial observation from lawful altitudes. The Supreme Court has specifically rejected blanket curtilage protection from aerial surveillance when conducted from public airspace.
C is wrong because subjective expectation of privacy alone isn't enough—it must also be objectively reasonable. Courts have ruled that fencing and signs don't create reasonable expectations of privacy against aerial observation from lawful altitudes, since anyone in an aircraft could potentially see the same things.
D is wrong because the legality of the activity is irrelevant to the privacy analysis. Even people engaged in illegal conduct can have legitimate expectations of privacy in certain circumstances—the Fourth Amendment doesn't disappear based on suspected criminality.
Study tip: Remember the two-part privacy test: subjective expectation plus objective reasonableness. For aerial surveillance, if the aircraft is at a lawful altitude in public airspace, the observation typically doesn't constitute a search.
- The resident of the apartment was charged with forgery. His attorney moved to suppress the evidence. What is the prosecution's strongest argument that the officer's entry and seizure were lawful? Select one.
Answer: The officer's entry was justified under the emergency aid exception to the warrant requirement.
The correct answer is B. The emergency aid exception allows officers to make a warrantless entry into a home if they have an objectively reasonable basis for believing that an occupant is seriously injured or imminently threatened with such injury. The 911 call reporting screaming and a struggle provided such a basis. Once lawfully inside under this exception, the officer could seize contraband or evidence of a crime that was in plain view. A is incorrect because hot pursuit involves chasing a fleeing felon; there was no pursuit here. C is incorrect because the plain view doctrine allows for the seizure of an item from a lawful vantage point; it does not, by itself, justify a warrantless entry into a protected area like a home. D is incorrect because the 911 call may have provided reasonable suspicion or even probable cause to believe a crime was occurring, but probable cause alone does not permit a warrantless entry into a home absent an exception.
- The individual moves to suppress the methamphetamine, arguing his initial detention was unlawful. How should the court rule on the lawfulness of the detention? Select one.
Answer: Lawful, because a warrant to search for contraband implicitly carries with it the limited authority to detain occupants of the premises while a proper search is conducted.
The correct answer is D. The Supreme Court held in Michigan v. Summers that officers executing a search warrant for contraband have the authority to detain the occupants of the premises while the search is being conducted. This is justified by the interests in preventing flight, minimizing risk to officers, and facilitating an orderly completion of the search. The detention is a limited seizure and does not require probable cause or reasonable suspicion specific to the person being detained. A is incorrect because the initial detention was not an arrest and did not require probable cause. B is incorrect as it misstates the holding of Summers. C is incorrect because reasonable suspicion is not the required standard for this type of detention during the execution of a search warrant.
- The student was charged with possession of marijuana. His attorney filed a motion to suppress the evidence. What is the likely outcome? Select one.
Answer: The motion will be denied, because the search was justified at its inception and was reasonable in scope.
The correct answer is C. Under New Jersey v. T.L.O., the Fourth Amendment applies to searches by public school officials, but they are subject to a lower standard than probable cause. A search is permissible if it is (1) justified at its inception (i.e., there are reasonable grounds for suspecting the search will turn up evidence of a violation of law or school rules) and (2) reasonable in scope (i.e., the measures adopted are reasonably related to the objectives of the search and not excessively intrusive). Here, the tip from another student provided reasonable grounds to suspect the student had vape pens, satisfying the first prong. Searching his backpack was directly related to finding those pens, satisfying the second prong. A is incorrect because student consent is not required for a search based on reasonable suspicion. B is incorrect because the standard is reasonable suspicion, not probable cause. D is incorrect because the Fourth Amendment does apply to school officials.
- The suspect's attorney moves to suppress the evidence found on the smartphone. What is the most likely outcome of the motion? Select one.
Answer: Granted, because police must obtain a warrant to search the digital contents of a cell phone, even when seized incident to arrest.
When you encounter Fourth Amendment questions involving cell phone searches, remember that the Supreme Court's 2014 decision in Riley v. California fundamentally changed the rules. Digital devices receive special protection due to their vast storage capacity and the intimate nature of the data they contain.
Answer A is correct because Riley established that police generally must obtain a warrant before searching the digital contents of a cell phone, even when the phone is seized incident to a lawful arrest. The Court recognized that cell phones are fundamentally different from physical items traditionally searched during arrests—they contain the "privacies of life" and require heightened constitutional protection.
Answer B is wrong because the officer's concern about remote data wiping doesn't automatically create an exigent circumstance. Riley specifically addressed this concern and noted that police can take reasonable steps to prevent data destruction (like turning off the phone or using a Faraday bag) without conducting a warrantless search of the contents.
Answer C reflects the pre-*Riley* approach and is incorrect. While police can seize phones incident to arrest for officer safety and evidence preservation, searching the digital contents requires additional justification under Riley.
Answer D is wrong because it focuses on the relatedness of evidence to the original crime. While this might be relevant to the scope of some searches, *Riley*'s warrant requirement applies regardless of whether the digital evidence relates to the arrest offense.
Study tip: For bar exam Fourth Amendment questions, always consider whether Riley applies when you see digital device searches. The case created a bright-line rule requiring warrants for cell phone content searches.
- You are representing the driver on a DUI charge. What is your strongest argument for suppressing all evidence obtained from the stop? Select one.
Answer: An anonymous tip, without further police corroboration of the alleged illegal activity, is insufficient to create reasonable suspicion.
The correct answer is B. Under Florida v. J.L., an anonymous tip must be reliable in its assertion of illegality, not just in its tendency to identify a determinate person. While the tip here identified the specific car, it lacked sufficient indicia of reliability regarding the claim of 'weaving.' The officer did not personally observe any suspicious behavior. The Supreme Court in Navarette v. California held that some 911 calls, particularly those reporting contemporaneous events like drunk driving, may have sufficient indicia of reliability, but a bare-bones, uncorroborated report like this one is vulnerable to challenge. This makes B the strongest argument. A is incorrect; reasonable suspicion is the standard for a traffic stop. C is incorrect as a report from minutes earlier is not stale. D is incorrect; a traffic stop is a seizure but not a full arrest.
- At a suppression hearing, the prosecutor argues that the man had no reasonable expectation of privacy in his conversation because he was in a glass phone booth visible to the public, and was violating a state statute. Is this argument likely to succeed? Select one.
Answer: No, because a person in a phone booth who shuts the door seeks to exclude the uninvited ear, creating a reasonable expectation of privacy in the conversation.
The correct answer is C. This fact pattern is based on the landmark case Katz v. United States. The Supreme Court held that the Fourth Amendment protects people, not places. A person who enters a phone booth, shuts the door, and pays the toll is entitled to assume that the words he utters will not be broadcast to the world. This creates a reasonable expectation of privacy that society is prepared to recognize as reasonable. The fact that the booth is glass and the person is visible is irrelevant to the privacy of the conversation itself. A is incorrect because it misstates the Katz holding. B is incorrect because one does not lose Fourth Amendment protections simply by engaging in criminal activity; the protection is against unreasonable searches for evidence of that activity. D describes the pre-*Katz* trespass doctrine, but the modern analysis focuses on the expectation of privacy, making C the more precise and controlling rationale.
- The suspect's attorney moved to suppress the laptops. What is the most likely outcome of the motion? Select one.
Answer: Denied, because the automobile exception permits a warrantless search of any container within a vehicle that may conceal the object of the search.
The correct answer is C. The automobile exception to the warrant requirement allows police to search a vehicle without a warrant if they have probable cause to believe it contains evidence of a crime. This search extends to the entire vehicle and any containers within it, including locked ones, where the evidence might reasonably be found. Because the officers had probable cause to believe the car contained stolen electronics, their search of the trunk and the locked briefcase was permissible. A is incorrect because under the automobile exception (United States v. Ross), the scope of the search is defined by the object of the search and is not limited by the presence of locked containers. B is incorrect because the justification for the search is the automobile exception, not a search incident to arrest, which has different scope limitations. D states a correct general principle but is not the specific legal rule that resolves the issue; the automobile exception is the dispositive doctrine.
