search and seizure Flashcards
sensory help- binoculars and dogs
not considered a search unless they use x-ray device, or come upon the curtilage of the home, so looking through binoculars to open windows across the street is fine.
effect of warrant
presumption of 4th amendment compliance
arrest warrant can search suspect’s home if
- police have reason to believe the suspect is home, and
- the suspect refuses to respond to police requests to open the door.
scope of search warrant
o A search warrant allows police to search the specified place for the specified contraband.
invalidation of warrant
o the warrant was not based on valid probable cause;
o the magistrate was not neutral and detached;
o the warrant failed to describe with particularity the thing to be seized or place to be searched (i.e., the warrant is too general); or
o the affidavit supporting the warrant was so lacking in probable cause that no rookie officer would have trusted it. For example:
the affidavit offers no objective support for its assertion; or
the information in the affidavit is obviously stale.
execution of warrant invalidates when
Warrant execution that “shocks the conscience” is unreasonable.
Knock and announce is NOT required
if the police have a reasonable suspicion that doing so will endanger the officers, lead to destruction of evidence, or cause the flight of the suspect.
o Probable cause
means a “fair probability,” and exists when there are facts and circumstances that lead a reasonable officer (objective standard) to conclude that the individual committed a crime (for an arrest) or that specific items related to criminal activity can be found at a particular location (for a search).
the permissible scope of a Terry stop
limited to:
in the exercise of due diligence;
to confirm or negate the suspicion.
• Routine Police Encounter
o If a police encounter in no way restrains the freedom of the individual (i.e., there is no use of force or show of authority followed by submission), it does not trigger the Fourth Amendment and requires no cause.
o Reasonable suspicion that crime is “afoot” may be established by:
police observations or other eyewitness reports to the officer;
a person’s flight from police in high-crime areas; or
an informant tip plus police investigation that corroborates the tip’s predictions.
tip for PC v. rs
• Unlike a tip that establishes PC, to establish RS, the tip does not have to indicate that the informant has “insider” access to the suspect.
if the RS that led to the Terry stop grows into PC during the stop
then the suspect can be arrested during a terry stop
anonymous tips and terry stops
needs to provide predictive info, not just that someone is standing at a bus-stop with an illegal pistol
plain view exception
the police observe the property while they are in a lawful vantage point (e.g., it is in public or they are otherwise lawfully in the place from whence they observe the item);
what police observe immediately establishes PC to justify the seizure; and
the officer has lawful access to the point of seizure (if the officer has to “get to” the item to seize it, they must have lawful authority to do so).
