What is the Silver Platter Doctrine and its effect?

A private party acting on his own does not trigger the 4th Amendment when he acquires evidence that the government later seeks to introduce in a criminal prosecution.


When a private party acts at the direction of a government agent or pursuant to an official policy to search an individual, is the 4th Amendment triggered?

Any search or seizure directed by the government is subject to 4th Amendment scrutiny


When is a person seized as the result of government action?

When a reasonable person in his position would not feel free to leave or otherwise terminate the encounter


More Info: Seizure


When is the 4th Amendment's reasonableness requirement triggered?

With any government seizure of a person or property.


What is the 4th Amendment protection if a reasonable person would feel free to leave or terminate a government encounter?

There is no seizure, and it does not trigger the reasonableness requirement.


When does a government seizure occur?

1. Physical force is used to restrain a suspect


2. The government makes a show of authority followed by submission


If a suspect is located in a naturally confined location (such as an airplane), what is the test for a seizure?

Whether a reasonable person would feel free to terminate the encounter with the government agent


What are all arrests?



What is a Terry Stop?

A brief investigatory seizure where the police require the suspect to interact with them, and which triggers the 4th Amendment


More Info: Terry Stop


What is the permissible duration of a Terry Stop?

The time necessary to confirm or deny the suspicion


What is the effect of the suspicion prompting a Terry Stop being confirmed?

The suspicion becomes probable cause, and an arrest is justified.


What is the effect of the suspicion prompting the Terry Stop being not confirmed?

The seizure must terminate.


Differentiate a Terry Stop from an arrest.

A Terry Stop is an investigation of reasonable suspicion, and an arrest is an instigation of an action.

2. Evidence will be found at a location


In applying for a warrant, what must the information presented to the magistrate not be?

Stale, meaning that enough time has passed such that the information is no longer good.


When will the method of warrant execution render the police action unreasonable?

The method of executing the warrant shocks the conscience.


What is the knock and announce rule?

Police must normally knock and announce their identity before entering a home to execute a warrant.

3. Lead to flight of the suspect


What is the effect of a violation of the knock and announce rule?

1. The police violate the 4th Amendment


2. The violation does not prompt evidence exclusion


What is the analysis for search and seizure questions?

Step 1: Determine whether there was a search or seizure

Step 2: Ask whether there was a valid warrant

a. If so, look for facts that indicate the warrant was defective and the police acted in bad faith when they relied on it


b. If not, then consider whether an exception applies.

Step 3: Does the search or seizure fall into one of the established exceptions:

a. If so, the search or seizure is reasonable

b. If not, the search or seizure is unreasonable


Without a warrant, the reasonableness of a search or seizure requires police to establish what?

Individualized suspicions that amounts to either probable cause or reasonable suspicion


When is probable cause always required?

For a full scale intrusion to:

1. Find evidence


2. Arrest

A full scale intrusion


What types of evidence establishes probable cause?

1. Eye witness accounts

2. Forensic evidence and tests

3. Suspect's own admissions or conduct

The totality of the circumstances test is used to assess the reliability of an informant's tip to establish probable cause. The factors considered are:

1. The reliability of the informant

2. The basis of the informant's knowledge


3. Corroboration by further investigation


Define reasonable suspicion.

A reasonable belief based upon articulable information {more than a mere hunch} that the suspect has or is about to engage in illegal or criminal activity.


More Info: Reasonable Suspicion


Reasonable suspicion will never justify what type of search or seizure?

An arrest or a full-blown evidentiary search


What will transform an officer's subjective opinion into a reasonable articulable belief?

When can a reasonable suspicion that crime is about to or has just occurred be established?

1. Police observations and eyewitness reports

2. Running from police in a high crime neighborhood

What is the effect of a tip that provides nothing more than existing information?

The tip does not establish even reasonable suspicion.


What is the permissible scope of a Terry Stop?

The time required for an officer acting in due diligence to:

1. Confirm


2. Deny the suspicion


How can reasonable suspicion rise to probable cause?

If during the investigatory stop the police officer obtains additional information rising to the level of probable cause, the Terry Stop may be escalated to an arrest and the suspect may be searched incident to that arrest.


How does an officer's improper subjective basis effect a Terry Stop?

The stop is still valid if there was an objectively reasonable basis for the stop.


When is no warrant required to seize property?

2. Victims


What is a Terry Search (frisk)? When is it justified?

A Terry frisk is a cursory protective search for weapons that create an imminent danger to an officer or others in close proximity.

A Terry frisk is justified only by reasonable suspicion that the suspect is armed and dangerous. It is not automatic because the police did a terry stop.


Differentiate the justification for:

Terry Stop v. Terry Frisk

Terry Stop: reasonable suspicion that a crime is happening or about to happen

Terry Frisk: reasonable suspicion that a suspect is armed and dangerous


What is the scope of a Terry Frisk?

The exterior of the clothing to determine if there is a weapon


What may an officer do if, in a Terry Frisk, the officer feels something he immediately knows is a weapon or contraband?

The plain touch doctrine: the officer may seize such contraband without a warrant.


What may an officer do if, in a Terry Frisk, the officer feels something he immediately knows is not a weapon but upon manipulation, feels may be contraband?

The manipulation exceeds the scope of the Terry Frisk and the seizure is unreasonable.


What are two circumstances where the Terry Frisk is extended beyond a person?

1. In an automobile, where police have reasonable suspicion a person stopped will have immediate access to a weapon


2. In a cursory sweep of the interior of a home, when police enter the home to serve a warrant based on reasonable suspicion that there are others who might be present and dangerous to the police

More Info: Standing for Exclusion


When can a defendant assert standing for exclusion on someone else's behalf?



What must a defendant show to prove standing for exclusion?

The defendant must first show that the 4th Amendment violation was directed against his 4th Amendment protection, not someone else's.

A defendant who has Fourth Amendment standing may invoke the exclusionary rule to prohibit the government from introducing evidence obtained as a direct or derivative result of an unreasonable search and seizure


What is the fruit of the poisonous tree doctrine?

Any additional evidence derived from an initial illegality, is tainted fruit of the poisonous tree and thus suppressible.


More Info: Fruit of the Poisonous Tree Doctrine


When is evidence tainted by fruit of the poisonous tree?

If there is a but-for connection between the evidence the prosecution seeks to admit and a violation of the defendant's constitutional rights.


Will a miranda violation qualify as a poison tree and taint further evidence?

No, the only consequence of a miranda violation is the inadmissibility of a confession.


What are the exceptions to fruit of the poisonous tree doctrine?

1. Independent source

2. Attenuation


3. Inevitable discovery


More Info: Exceptions to the FPTD


What is the independent source exception to the fruit of the poisonous tree doctrine?

What is the inevitable discovery exception to the fruit of the poisonous tree doctrine?

Future evidence is not tainted if the police establish they would have inevitably discovered the evidence through a different and independent source.


What is the attenuation exception to the fruit of the poisonous tree doctrine?

Evidence may be so distant from the initial illegality that the taint of the poison is purged and the evidence is admissible.


More Info: Attenuation


What is a common source of the attenuation exception?

When police obtain a voluntary confession following an unlawful arrest (as long as it does not come right after).


What factors support attenuation?

1. Evidence discovered in a different location

2. The passage of time between discovery

3. A different officer discovered


4. A valid miranda warning


What is the good faith exception to exclusion?

Inapplicable when:

1. A reasonable officer would not have relied upon a warrant that is later found to be invalid

2. An officer lies or misleads the magistrate

3. Where the warrant is so facial defective that an officer should not rely upon it
