Crim Pro Flashcards
4th Amendment rule statement
the 4th amendment prohibits unreasonable searches and seizures. in order to assert a 4th amendment violation, a defendant must demonstrate government conduct and that he had a reasonable expectation of privacy
- government conduct
to demonstrate government conduct, the defendant must prove that the government or police were involved in the unreasonable search and seizure
- reasonable expectation of privacy
defendant must also prove that he has a reasonable expectation of privacy as to the places searched and items seized by the government
- seizure of a person overview
a seizure occurs if under the totality of circumstances, a reasonable person would not feel free to leave. types of seizure include arrest, stop and frisk, police checkpoints, and traffic stops (CATS)
a. arrest
an arrest in D’s home generally requires an arrest warrant. however, an arrest warrant is not required to make an arrest in a public place. if an officer witnesses a felony or misdemeanor, he can make a warrantless arrest. also, if an officer has probable cause to believe that a felony has been committed (not witnessed by the officer), an officer can make a warrantless arrest
*if a confession is too closely tied to the illegal arrest, it may be suppressed
b. terry stop (investigatory stop) and frisk
an officer can stop a person if he has reasonable suspicion that the person is engaged in or has engaged in criminal activity
*a mere hunch is not enough
*If an officer makes an unconstitutional investigatory stop, and learns during the stop that the suspect was subject to a valid arrest warrant, arrests the suspect, and seizes incriminating evidence during a search incident to that arrest, then the evidence the officer seizes as part of the search incident to the arrest is admissible.
c. police checkpoints
police checkpoints are generally valid, as long as the stop is conducted in a non-discriminatory manner and the purpose of the checkpoint is for an articulable reason beyond general crime prevention. for example, DUI checkpoints are legal, but checkpoints that are generally looking for contraband are not
d. traffic stops
traffic stops are valid if the officer has reasonable suspicion or probable cause that a traffic law has been violated
- search
a search occurs when the governmental conduct violates the defendant’s reasonable expectation of privacy
- the use of sense-enhancing technology that is not in use by the general public constitutes a search
- an inspection conducted from the air at a height of at least 400 feet does not violate a reasonable expectation of privacy and therefore is not a search for the purposes of the Fourth Amendment
a. valid search warrant
to be valid, a warrant must 1. be issued by a detached and neutral magistrate, 2. be based upon probable cause, and 3. describe with particularity the defendant and crime or the places to be searched and items to be seized
subject to certain exceptions, under the “knock and announce” rule, the police must also announce their presence and state their purpose
finally, evidence collected in violation of D’s 4th amendment right to privacy may nonetheless be admissible if police officers acted in good faith reliance upon a defective search warrant as measured by a reasonable person standard
*anticipatory search warrants are permitted, must be probable cause to believe that the triggering condition will occur and, if that condition does occur, there is a fair probability that contraband or evidence of a crime will be found in a particular place
b. exceptions to warrantless search
warrantless searches constitute a 4th amendment violation, and evidence seized during the search will be inadmissible unless subject to an exception.
SCAPES
stop & frisk, consent, automobile exception, plain view, exigent circumstances, and search incident to lawful arrest
(i) terry stop (investigatory stop) and frisk)
an officer can stop a person if he has reasonable suspicion that the person is engaged in criminal activity
frisk of a person: the officer can then frisk or pat down the outer clothing of D for the purposes of officer safety. if the officer feels an object whose identity is immediately obvious as contraband, it can be seized during the frisk under the “plain feel” exception
automobile frisk: if an officer lawfully stops a car (reasonable suspicion that a traffic violation has occurred), the officer may frisk the inside of the car if she has reasonable suspicion that there is a weapon in the car. however, the officer can only frisk the areas of the car that may contain a weapon
(ii) search incident to lawful arrest
a search incident to a lawful arrest must be reasonable in scope and incident to a lawful arrest that is based upon probable cause
- lawful arrest
- scope of search: the police may conduct a contemporaneous search of the arrestee and his immediate surrounding area, such as pockets and containers. if the arrestee is at home, the police can search the closets or other spaces adjoining the place of arrest in the home where an attack is likely. if the arrestee is in a vehicle, the police may search the glove compartment if the arrestee is within reaching distance of it or it is reasonable that evidence might be in the vehicle
(iii) automobile exception
under the automobile exception, the police can search any part of D’s car if they have probable cause that it contains contraband or other evidence of a crime
(iv) plain view
no warrant is required to seize evidence in plain view if the police are lawfully in the location from which the evidence can be viewed and the criminal nature of the item is immediately apparent
(v) exigent circumstances
under a totality of circumstances test, exigent circumstances may make a warrantless search constitutional if probable cause exists.
exigency can be determined by many factors, including
- hot pursuit of a fleeing felon,
- reasonable apprehension that a delay in getting a warrant would result in immediate danger of evidence destruction, or
- police and/or public safety
(vi) consent
if a party consents to a search, a warrant is not required. the consent must be voluntary, and there must be no threats of harm, compulsion, or the false assertion of lawful authority
*a third party’s consent to a search is not invalid because he lacks the authority to consent, so long as the police reasonably believe that he does have such authority
c. exclusionary rule and “fruit of the poisonous tree”
the exclusionary rule applies to evidence seized as a result of government illegality (4, 5, or 6A), as well as the “fruit of the poisonous trees,” which is any evidence derived from the illegal government action
(i) exceptions to the exclusionary rule
- inevitable discovery through lawful means
- independent source unrelated to the taint
- passage of time
- good faith reliance on validity of warrant
- isolated negligence by law enforcement personnel doesn’t necessarily trigger exclusionary rule
5th Amendment rule statement
the 5th amendment provides that no person shall be compelled in a criminal case to testify against himself. the right applies to testimonial evidence coercively obtained by the police
*the Fifth Amendment privilege does not extend to the custodian of corporate records (because the request for production is being made to the custodian in his capacity as a corporate employee)
