Which amendment protects individuals against unreasonable searches and seizures?
Fourth Amendment
First Amendment
Sixth Amendment
Fifth Amendment
The Fourth Amendment specifically guards against unreasonable searches and seizures by the government. It sets the constitutional standard for search warrants and related procedures.
Probable cause is best defined as:
Evidence sufficient to convict beyond a reasonable doubt
A reasonable belief based on factual evidence that a crime has been or will be committed
A hunch or intuition by an officer
Proof by a preponderance of evidence
Probable cause exists when facts and circumstances would lead a reasonable person to believe a crime has occurred or evidence is present. It is a lower standard than proof beyond a reasonable doubt.
A search warrant must be supported by:
An officer's unverified hunch
A neighborhood rumor
An affidavit establishing probable cause
A suspect's criminal history alone
Search warrants require an affidavit sworn under oath that sets out sufficient facts establishing probable cause. Mere rumors or unverified hunches do not meet this standard.
Which exception allows police to conduct a warrantless search of an arrestee and the area within their immediate control?
Exigent circumstances
Search incident to arrest
Consent search
Plain view doctrine
The search incident to arrest exception permits officers to search the person and the area within their immediate control for weapons or evidence. This protects officer safety and prevents evidence destruction.
What does the exclusionary rule provide?
Police cannot question suspects without a lawyer
Defendants are excluded from certain trials
Only eyewitness testimony is allowed
Evidence obtained unlawfully is inadmissible in court
The exclusionary rule bars evidence obtained in violation of the Fourth Amendment from being used in court. It serves as a deterrent against unlawful police conduct.
Which scenario illustrates the plain view doctrine?
An officer hears suspicious noises before entering
An officer properly stops a suspect on the street
An officer breaks a window to look inside a home
An officer seizes a stolen TV visible through an open window where the officer is lawfully standing
Plain view requires the officer to be lawfully present and to immediately recognize the item as incriminating. Seizing evidence visible in that context is permitted without a warrant.
Which condition best describes exigent circumstances justifying a warrantless entry?
Suspect consents to entry
Officer uses a K-9 sniff outside a home
Imminent risk of evidence destruction
Officer plans to seek a warrant next day
Exigent circumstances exist when officers reasonably believe that waiting for a warrant would endanger lives or lead to the destruction of evidence. This exception permits immediate action.
Under what condition is a consent search valid?
Officer threatens to call immigration authorities
Consent is given while the person is in custody
Officer falsely claims to have a warrant
Consent is given voluntarily and without coercion
Voluntary consent must be the product of free will, without duress or coercion. Courts assess the totality of the circumstances to determine voluntariness.
Which is NOT a requirement for a valid search warrant?
Particular description of the items to be seized
Judge's signature
Description of the place to be searched
General authority to search the entire property for any crime
The Fourth Amendment requires particularity in warrants, limiting searches to described places and items. A blanket authority to search for any crime violates this principle.
A search incident to arrest may include a search of:
Personal documents of a third party
The arrestee's cell phone data without a warrant
The entire residence if the arrest occurs in a home
The area within the arrestee's immediate control
Search incident to arrest is limited to the arrestee's person and areas from which they might obtain a weapon or destructible evidence. It does not extend to all premises.
Which Supreme Court case established the "reasonable expectation of privacy" test?
Katz v. United States
Terry v. Ohio
Mapp v. Ohio
Chimel v. California
Katz v. United States introduced the two-part test requiring a subjective expectation of privacy that society recognizes as reasonable. It broadened Fourth Amendment protections.
What does the "fruit of the poisonous tree" doctrine exclude?
Voluntary statements by the defendant
Witness testimony independent of the search
Evidence derived from an illegal search or seizure
Evidence obtained under a valid warrant
The doctrine bars not only illegally obtained evidence but also evidence derived from it. Its purpose is to deter unlawful police conduct.
A "knock-and-talk" procedure requires officers to:
Obtain written consent before knocking
Forcefully enter without announcement
Knock, announce their presence, and request entry
Execute an arrest warrant only
Knock-and-talk involves officers knocking on the door, announcing their authority and purpose, and then seeking voluntary entry. It respects the warrant requirement absent exigent circumstances.
Which statement about border searches is correct?
They are limited to searching persons only
They always require probable cause
They may be conducted without a warrant or probable cause
They cannot include searches of electronic devices
Border searches are an exception to the warrant and probable cause requirements, allowing routine inspections of people and goods at the border. Limitations may apply to highly intrusive searches.
The special needs doctrine authorizes suspicionless searches when:
They serve a general law enforcement purpose
They address governmental needs beyond ordinary crime control
They follow execution of a valid warrant
They target a specific individual for a crime
Special needs searches are upheld when designed for non-law enforcement purposes, such as safety screening or administrative programs. They hinge on balancing privacy against governmental interests.
An anticipatory search warrant is one that:
Is activated upon occurrence of a specified future event supported by probable cause
Does not require a judge's signature
Is limited to searches for digital evidence
Can be executed only after the crime is fully committed
An anticipatory warrant rests on probable cause that a triggering condition - such as delivery of contraband - will occur. The warrant becomes valid only after the condition is met.
Which dog-sniff scenario is considered a search requiring a warrant?
Sniffing a vehicle parked on a public street
Sniffing luggage in a public airport terminal
Sniff during a lawful traffic stop on the highway
Sniffing the front porch of a home without a warrant
Using a trained dog on the curtilage of a home constitutes a search under Florida v. Jardines and requires a warrant. Public-area sniffing generally does not implicate the Fourth Amendment.
Police obtain seven days of historical cell-site location data without a warrant. Under Carpenter v. United States, this action is:
Unconstitutional because a warrant is required for CSLI
Valid if obtained by subpoena
Permissible as an administrative inspection
Constitutional under the third-party doctrine
Carpenter held that accessing historical cell-site location information is a search under the Fourth Amendment. Law enforcement must obtain a warrant supported by probable cause.
Police hear screams from inside a home and force entry without a warrant, discovering illegal drugs. At trial the drugs are:
Excluded because no knock was announced
Admissible only if occupants consented later
Admissible under the emergency aid exigent exception
Excluded under the exclusionary rule
The emergency aid exception allows police to enter without a warrant when they reasonably believe someone inside is in imminent danger. Evidence seized under this exception is admissible.
Which case limited the search incident to arrest exception by requiring a warrant to search a seized cell phone?
United States v. Robinson
Riley v. California
Chimel v. California
Terry v. Ohio
Riley v. California held that digital data on a cell phone cannot be searched incident to arrest without a warrant. The Court recognized the vast privacy interests in modern phones.

Cheat Sheet

  1. Fourth Amendment Fundamentals - The Fourth Amendment shields us from unreasonable searches and seizures by setting clear privacy boundaries that law enforcement must respect. Think of it as your personal privacy shield in the Constitution, ready to fend off uninvited intrusions.
  2. What Makes a Warrant Valid? - A valid search warrant isn't magic - it requires probable cause, a precise description of the place to be searched, and a neutral magistrate's approval. Nail these elements and you've got a rock-solid warrant that courts can't easily knock down.
  3. Exceptions to the Warrant Rule - Sometimes police can bypass a warrant in emergencies (exigent circumstances), with consent, or when evidence is in plain view. These carve-outs keep the law flexible but still protect your rights when every second counts.
  4. Landmark Case: Mapp v. Ohio - In Mapp v. Ohio, the Supreme Court ruled that evidence obtained through unconstitutional searches is inadmissible in state courts. This "exclusionary rule" packs a punch by discouraging illegal searches and protecting your privacy rights.
  5. Good-Faith Exception - The "good-faith" exception saves evidence when officers rely on a defective warrant they honestly believe is valid. It's a courtroom lifeline that balances mistakes with the need to uphold justice.
  6. Knock-and-Announce Rule - Before barging in, officers usually have to knock, announce their purpose, and wait - unless safety or evidence destruction is at stake. This rule ensures fairness and gives occupants a chance to comply peacefully.
  7. Reasonable Expectation of Privacy - From phone booths to smartphones, Katz v. United States set the test: Would a reasonable person expect privacy in this situation? If yes, the Fourth Amendment steps in to protect that space.
  8. Chimel v. California Limits - After an arrest, officers can search only the area within the suspect's immediate control for weapons or evidence. Chimel drew this boundary to prevent sweeping, unchecked searches.
  9. Plain View Doctrine - If an officer is lawfully present and spots incriminating evidence in plain sight, they can seize it without a warrant. It's like finding a free bonus clue when everything else is above board.
  10. Executing Lawful Searches - Proper procedure means getting a warrant when required, sticking to its scope, and honoring all constitutional safeguards. Master these steps and you'll navigate search-and-seizure rules like a pro.
