1. Thompson is suspected of running a counterfeiting operation out of his garage. The
garage is attached to the dwelling. Without a warrant, three officers step onto his
curtilage, shine a flashlight into the garage, and take a quick look. They observe a
number of what appear to be $100 bills hanging from a clothesline. Was the observation
into the garage lawful?
ANSWER: No, because the officers physically intruded on a constitutionally protected
location without either a warrant or an exception to the 4th Amendment.
RATIONALE: The garage is part of the curtilage, which is protected by the Fourth
Amendment. Physical intrusion without a warrant or exception violates constitutional
protections.
2. Agents develop reasonable suspicion that Wooster is operating a stolen credit card
ring. Upon seeing Wooster driving in his car one afternoon, the agents follow him. When
he arrives at a shopping mall, the agents approach him, identify themselves, and tell him
to put his hands on his automobile. One of the agents frisks him and, in the upper left hand
pocket, feels what is immediately apparent to him as a stack of credit cards bound by a
rubber band. The agent removes the credit cards and, ultimately, determines that they are
stolen. Wooster's motion to suppress the credit cards will be -
ANSWER: Granted, because the agents performed an illegal "frisk" of Wooster.
,RATIONALE: A frisk requires reasonable suspicion that the person is armed and
dangerous. The agents lacked any basis to believe Wooster was armed, making the frisk
unconstitutional.
3. Johnson is arrested for drunk driving and failing to pay child support. He agrees to
share information with the police to avoid prosecution. Having been personally involved in
every aspect of an ongoing stolen paycheck operation, Johnson explained the intimate
details to the police of what he saw and did with Fred, a co-criminal. Based on his
statements alone, the officers seek a search warrant for the co-criminal's premises where
Johnson stated he saw many of the stolen checks the day before. Can Johnson's statement
alone establish Probable Cause to support a warrant application?
ANSWER: Yes, because Johnson's statements amount to probable cause under a totality of
the circumstances using the Illinois v. Gates test.
RATIONALE: Under Illinois v. Gates, a totality of the circumstances test applies, and
statements from a participant in the crime can establish probable cause if they provide
sufficient detail and indicia of reliability.
4. An officer is walking down a public sidewalk in the early evening hours, just after dark.
Glancing in the direction of Sweeney's home, the officer notices that, while Sweeney has
drawn the curtains in the front window, there is a gap through which the officer sees what
he knows to be a large marijuana plant. The following morning, based solely upon this
information, the officer seeks a search warrant for Sweeney's home. The request for a
search warrant will be -
ANSWER: Granted, because the officer did not violate Sweeney's reasonable expectation
of privacy in making the observation on which the search warrant will be based.
RATIONALE: The officer was on a public sidewalk, and the observation was made through
a gap in the curtains, which does not violate a reasonable expectation of privacy under
the plain view doctrine.
5. Marsh checked a suitcase at the airline counter and got onto an airplane. Before the
suitcase was placed on the airplane, it was sniffed by a drug detection dog. The dog
indicated that drugs were located inside which established probable cause to search the
, suitcase. With this knowledge, two DEA agents entered the airplane, approached Marsh,
identified themselves, and asked him if they could look in the suitcase he had checked at
the counter. Marsh stated, "I'm not traveling with a suitcase." Because the plane wasn't
scheduled to take off for an hour (and Marsh didn't think he would miss the plane), Marsh
voluntarily agreed to accompany the agents to the suitcase, was shown the suitcase, and
was asked again if they could open it. Again, Marsh denied ever seeing the suitcase. The
agents opened the suitcase and discovered contraband inside. At trial, the contraband
should be -
ANSWER: Admitted, because Marsh abandoned the suitcase.
RATIONALE: By denying the suitcase was his, Marsh abandoned any reasonable
expectation of privacy he had in the suitcase, and therefore there was no 4th Amendment
intrusion.
6. Perry is a paid police informant and has provided reliable information to officers on
seven out of seven occasions. On January 7, 2000, Perry personally witnessed four
personal-use drug transactions take place in Joe Clark's apartment. On November 28,
2000, Perry tells the officer about these observations. The officer applies for a search
warrant for drugs based solely on this information. The request for the search warrant
should be -
ANSWER: Denied, because the information provided by Perry is inadequate to establish
probable cause.
RATIONALE: The information is stale because almost eleven months has passed since the
drugs were seen in Clark's apartment and therefore there is no probable cause there are
drugs there NOW.
7. Which Supreme Court case established the "reasonable expectation of privacy"
standard?
ANSWER: Katz v. United States (1967)
RATIONALE: Katz established that the Fourth Amendment protects people, not places, and
requires both a subjective and objective expectation of privacy.
