Criminal Procedure Flashcards
When does probable cause exist?
Probable cause exists when a reasonably prudent person would believe that a suspect has committed or is committing a crime.
Requirements for a Valid Arrest
Any arrest must be based on probable cause.
Arrest warrants are generally not required before arresting someone in a public space.
A non-emergency arrest of an individual in their home does require an arrest warrant.
Effect of an Invalid Arrest
An unlawful arrest, by itself, has no impact on any subsequent criminal prosecution.
Terry Stop Rules
The police have the authority to briefly detain a person even if they lack probable cause to arrest. In order to make such a stop, they must have a reasonable suspicion supported by articulable facts of criminal activity.
Reasonable suspicion is more than just vague suspicion and less than probable cause. Whether or not police have it depends on a totality of the circumstances.
Rules for Relying on Information from Informants
When reasonable suspicion is based on an informant’s tip, there must be an indicia of reliability to be sufficient.
Automobile Stops
The police may not normally stop a car unless that have at least reasonable suspicion that the law has been violated. An automobile stop constitutes a seizure of all occupants. Officer may order occupants out of the car.
During a routine traffic stop, a dog sniff is not a search so long as the police do not extend the stop longer than is necessary to issue a ticket or conduct normal inquiries. An alert by a dog may be the basis for a probable cause search.
Roadblocks that do not see incriminating information are constitutional (i.e. border crossings, weigh stations, etc.)
An officer’s pretextual reason for stopping a car is irrelevant so long as the stop was legal.
Drug Sniffing Dogs
Not a search of a car and may be the basis of probable cause.
Cannot be used outside a suspect’s home.
Who falls under the purview of “government” for government conduct?
The publically paid police, regardless of whether on or off duty.
Any private individual acting at the direction of public police.
Privately paid police (store security, subdivision police, campus police, etc.) are not government unless they are deputized with the power to arrest.
Standing to Object to a Search
In order to object to a governmental search, one must have standing to object to the search, meaning they must have ah d a reasonable expectation of privacy in the area or item being searched.
Automatic Categories of Standing
Ownership of the place searched
If you live on the premises searched.
Overnight guests of the place being searched.
Ownership of the physical property searched, only if you have a reasonable expectation of privacy.
No Standing Categories
You have no expecation of privacy and therefore no standing to challenge anything you hold out to the public every day. These include:
The sound of your voice
The style of your handwriting
The paint on the outisde of your car
Account records held by a bank.
Monitoring the location of your car on the public street or in your driveway.
Anything seen in open fields
Anything seen from public air space
The odors eminating from your luggage or car.
Your garbage set out on the CURB for collection.
Warrant Requirements
Probable Cause: Meaning a fair probablility that contraband or evidence of a crime will be found in the area searched.
Particularity: The warrant must state with particularity the place to be searched and the items to be seized.
The warrant may be anticipatory, meaning it can request to search an area for items even if the officers do not blieve the items are currently there, so long as they have probable cause to believe they will be there are the time searched.
A warrant cannot be solely based on an anonymous tip. Whether or not an informant is enough for proable cause will depend on the totality of the circumstancs, the informants credibility and knowledge.
Search Incident to Arrest
The arrest be lawful, otherwise the search will be unlawful.
The arrest and search must be contemporanious as to time and place.
The scope is limitted to the person and the areas within the person’s wingspan.
With automobiles, they may search the interior of a car icnident to arrest if the arrestee is unsecured and may reutrn to the vehicle or if the police reasonably believe that evidence of the offense FOR WHICH THE PERSON WAS ARRESTED, may be found in the vehicle.
Cell Phones
Police may not seach digital information of a cell phone during a search incident to arrest must the physical attributes of the phone may be searched (i.e. taking it apart to check for drugs).
Automobile Exception to Warrants
If the police have probable cause, they may search anything or anybody in the entire car, including the trunk and any packages or luggage inside so long as they could reasonable contain the item.
This probable cause can arise after the car is stopped but must arise before anyone or anything is searched.
Plain View
A police officer who is legitimately present at a location and views an item that immediately apparent as contraband or fruit of a crime may seize it.
Consent
For consent to be valid it must be voluntary.
Where two or more people have a right to use a piece of property, either can consent to a search. If one person consents and the other objects, police may not search. However, if the co-occupant who objects leaves voluntarilly or is removed lawfully (i.e. arrested) the remaining party may still consent and the search will be valid.
Also, anyone with apparent authority can validly consent to a governmental search.
Stop and Frisk
A Terry stop is a brief detention for the purpose of investigating suspicious conduct and the legal standard is reasonable suspicion. The pat down of the outer clothes is merely to check for weapons, although immediately recognized contraband can be seized, and if an arrest is made, a lawful search incident to arrest may follow.
If an officer reasonably blieve a person may be armed an dangerous during a traffic stop, they may conduct a frisk of the person and they may search the limitted areas of the vehicle in which a weapon may be placed.
Evanscent Evidence
Evanescent evidence is evidence that might dissapear quickly if police took the time to get a warrant.
Blood samples in DUI cases must get a warrant if its at all practical to do so.
A police officer can scrape under a suspects fingernails without a warrant because otherwise the defendant might wash his hands.
Hot Pursuit
If the police are within 15 minutes behind the fleeing felon, it is hot pursuit. Otherwise, its too late.
If they are truly within hot pursuit, they can enter anyone’s home without a warrant and any evidence in plain view will be admissable.
Inventory Searches
Before incarceration of an arrestee, the police may search the arrestees personal belongings and the arrestees entire vehicle including any closed containers.
Emergency Aid/Community Caretaker Exception
Justifies a warrantless search if the officer faces an emergency that threated the health or safety of an individual or the public.
