Criminal Procedure Flashcards
What does the 4th amendment prohibit
If there is a search or seizure by a government agent, then the Fourth Amendment applies.
o Does not protect against private actors
What are the 3 ways to satisfy the 4th amendment?
• Method #1: Valid warrant + proper execution.
A valid warrant requires probable cause, particularity, and must be issued by an unbiased magistrate. Officers should follow warrant limits and generally should knock and announce
their presence.
Note: An arrest warrant is not needed if the suspect is in a public place. An arrest warrant is needed if D is at his home or at the home of a third party (in the latter case, a search warrant is also needed).
• Method #2: Good faith or a reasonable mistake by the officer saves a defective warrant.
This is not present if there are serious problems with the affidavit (e.g., it is based on an officer’s lies), search warrant, or magistrate (e.g., if she is not neutral).
• Method #3: exceptions exist (check other cards)
Criminallaw/procedure Where does the 4th amendment apply?
Defendant must have a reasonable expectation of privacy as to the places searched or items seized
How is seizure of a person determined
o By means of physical force OR show of authority, a person’s freedom of movement is restrained
o Test—under the totality of circumstances, would a reasonable person not feel free to leave
o Types of Seizure—Arrest, stop and frisk, police checkpoints, and traffic stops
a. Arrest
Generally, requires an arrest warrant
Warrantless arrest allowed if an officer has probable cause to believe that a felony has
been committed
When is an arrest allowed when there is NOT an arrest warrant?
Warrantless arrest allowed if an officer has probable cause to believe that a felony has
been committed
When is a Terry Stop allowed?
Terry Stop (Investigatory Stop) and Frisk
Valid when an officer has reasonable suspicion that someone is engaged in criminal activity
A “stop” (also known as a “Terry stop”) is a limited and temporary intrusion on an individual’s freedom of movement short of a full custodial arrest. Merely approaching a person, but not restricting the person’s movement in any way, does not constitute a detention.
A stop is justified on the reasonable suspicion, based upon articulable facts, that the detainees are or were involved in illegal activity.
When are police check points valid?
Valid if:
• Done in a non-discriminatory manner; and
• There is an automobile-related reason for the checkpoint
Example 1: A DUI checkpoint is legal because it is done for the purpose of preventing drunk driving (so long as it is conducted in a non-discriminatory manner).
when are traffic stops allowed?
Valid if the officer has reasonable suspicion or probable cause that a traffic law has been violated
Exam Tip 2: A recent question provided a statute that allowed an officer to arrest a person for a traffic violation if the officer had probable cause to believe the person had violated the statute
When does a search occur ( Very basic definition)
Occurs when government conduct violates the defendant’s reasonable expectation of privacy
Valid Search Warrant
A search conducted pursuant to a valid warrant is generally constitutional
To be valid, the warrant must:
a) Be issued by a neutral magistrate;
b) Be based upon probable cause; and
c) Describe with particularity the places to be searched and the items to be seized
List of the exceptions to a search warrant (ASPACE)
- Automobile Exception
- Search Incident to arrest
- Plain View
- Administrative Searches
- Consent
- Emergency Circumstances.
Automobile Exception:
Officers can search an automobile if they have probable cause to believe that evidence, instrumentalities, or fruits of a crime exist within it.
Tip: this includes the trunk if there is probable cause to believe evidence is in the trunk
Search incident to arrest exception
At the time of a lawful arrest (or “contemporaneous” with it), an officer may conduct certain searches of the arrestee (including his person, clothing, and his “wingspan” or grabable space) without a warrant in order to keep the officer safe and to preserve evidence.
Exception if the arrestee is in a vehicle: once the arrestee is secured, the police officer can only search the vehicle if it is reasonable to believe it contains evidence of the crime for which the suspect was arrested
Scope—defendant and the immediate area (i.e., wingspan)
o In arrestee’s home—can search areas within reach or where others may be hiding
o In a vehicle—can search glove compartment if within reach of defendant or if it is reasonable that evidence of the offense of arrest may be found
Tip: the officer may not search the trunk under this exception.
Plain View Exception
An officer, who is lawfully present in the area that he is in, may seize an item if it is “immediately apparent that it is contraband or evidence of a crime.”
Tip: this extends to other senses as well (plain smell and plain feel).
Emergency Circumstances
this comes up
(1) when an officer is in hot pursuit of a suspect
(Tip: there must be probable cause to believe that the suspect has committed a crime and he is in a particular place),
(2) if there is a serious injury or threat of injury, or
(3) if evidence of a crime likely will disappear before a warrant can be obtained.
A Terry stop and frisk is an exception where only reasonable suspicion is needed. For a Terry
stop, the officer needs reasonable suspicion that criminal activity is afoot. For a Terry frisk, the officer needs a reasonable belief that the suspect is armed and dangerous.
( Can do automobile frisk for reasonable belief weapon in car, but search limited to where might be weapon)
Tip: the officer can only frisk for weapons.
Administrative Search exception
this tends to commonly come up in three ways on the MBE:
(1) officers can search arrestees and impounded vehicles,
(2) public school officials can search students and their personal effects (e.g., backpack, purse, lockers, etc.) upon reasonable suspicion, and
(3) random drug testing is permitted for public school children involved in any extracurricular activity
Consent Exception for Searchs
If one with actual or apparent authority to consent gives consent voluntarily, officers may search the areas to which they understand the consent to extend.
- Cannot exceed scope of consent
- Must be voluntary (no threats, compulsion, or false assertion of lawful authority
Tip: a cotenant can consent to search of areas over which he has control but other cotenants who are present may revoke the consent.
What does the exclusionary rule for 4th amendment do?
Excludes evidence obtained as a result of the government’s violation of the 4th Amendment
Also excludes “fruits of the poisonous tree”—other evidence obtained as a result of the violation
What are the 5 exceptions to the exclusionary rule?
But, it can still be used (SIICKA)
if D does not have standing,
for impeachment,
if discovery was inevitable (or if there was an independent source or the taint disappeared),
in civil (and other non-criminal) proceedings,
or if the knock and announce rule was violated.
Attenuation
(Standing, Impeachment, inevitable discovery, civil proceedings, knock and announce)
3) Passage of Time (Attenuation)
The chain of causation between the primary taint and the evidence has been so attenuated as to “purge” the taint. Both the passage of time and/or intervening events may attenuate the taint.
What does the 5th amendment protect?
- Provides that no person shall be compelled in a criminal case to testify against himself
- Often called the right against self-incrimination
• Applies to testimonial evidence coercively obtained by police
