Laws of Arrest Flashcards

Under California Penal Code § 836, a peace officer can make a warrantless arrest for a misdemeanor under which of the following circumstances?

Answer: The officer has probable cause to believe the person committed a public offense in the officer's presence.

California Penal Code § 836(a)(1) explicitly states that a peace officer may make a warrantless arrest when they have probable cause to believe that the person to be arrested has committed a public offense (which includes misdemeanors) in the officer's presence. Reasonable suspicion is a lower standard of proof and is sufficient for a detention, not a warrantless misdemeanor arrest. Information from an informant, while potentially helpful in building probable cause, does not by itself satisfy the 'in the officer's presence' requirement for most misdemeanors. A prior conviction is not grounds for a new arrest.

An officer is dispatched to a department store where a loss prevention agent has detained a person for shoplifting. The loss prevention agent, a private person, states they saw the individual conceal merchandise and walk past all points of sale without paying. For the officer to accept the private person's arrest, which condition must be met according to PC § 837?

Answer: The misdemeanor offense must have been committed or attempted in the private person's presence.

According to California Penal Code § 837, a private person may arrest another for a public offense committed or attempted in their presence. When the officer arrives, their role is to take custody of the arrested person. The validity of the private person's arrest for a misdemeanor hinges on the offense having occurred in the private person's presence, meaning it was apparent to their senses.

Which of the following is the best definition of 'probable cause' to arrest?

Answer: A set of facts that would cause a person of ordinary care and prudence to entertain an honest and strong suspicion that the person to be arrested is guilty of a crime.

Probable cause is the standard required to make an arrest. It is defined as having enough facts and circumstances to lead a reasonable and prudent person to believe that a crime has been committed and that the person to be arrested is the one who committed it. It is more than a mere hunch but less than the evidence needed for a conviction (proof beyond a reasonable doubt).

An officer observes a man walking down the street at 2 AM in a residential area, carrying a crowbar and a flashlight. The man is looking into the windows of parked cars. The officer temporarily detains the man to investigate. What legal standard did the officer need to lawfully detain the man?

Answer: Reasonable suspicion

A detention, or a temporary stop, requires reasonable suspicion. Reasonable suspicion is a legal standard of proof that is less than probable cause. It must be based on specific and articulable facts that would lead a reasonable officer to believe that criminal activity is afoot. The man's actions, time of day, and possession of tools commonly used for burglary would create reasonable suspicion. Probable cause would be needed for an arrest, and proof beyond a reasonable doubt is the standard for a criminal conviction.

A peace officer has probable cause to believe that a person has committed a felony. However, the felony was not committed in the officer's presence. According to PC § 836, what is the officer's authority to arrest?

Answer: The officer may make a warrantless arrest.

California Penal Code § 836(a)(3) authorizes a peace officer to make a warrantless arrest when they have probable cause to believe that the person to be arrested has committed a felony, whether or not the felony was actually committed in the officer's presence. This is a key distinction between the arrest powers for felonies and misdemeanors.

Which of the following is NOT required to be given to a person being arrested?

Answer: The Miranda warning

While it is a common misconception, the Miranda warning is only required when a person is subjected to custodial interrogation (i.e., they are in custody and being questioned by law enforcement). It is not required at the moment of every arrest. The other elements—informing the person of the intent to arrest, the cause of the arrest, and the authority to make the arrest—are fundamental components of a lawful arrest procedure.
