Penal Code §835 defines an arrest as being made by 'an actual restraint of the person, or by submission to the custody of an officer.' The person arrested may be subjected to such restraint as is reasonable for the arrest and detention. Verbal statements (a), summoning police (c), and witness identification (d) do not by themselves constitute an arrest under §835.

Penal Code §835 expressly allows that the arrestee 'may be subjected to such restraint as is reasonable for his arrest and detention.' Excessive or punitive restraint exceeds this authority and exposes the guard to civil and criminal liability. Handcuffs are permissible if reasonable, but the law does not require them (b); 'whatever force is necessary' (a) is not the statutory standard; no restraint at all (d) would defeat the arrest.

Penal Code §835 lists 'submission to the custody of an officer' as one of the two ways an arrest is made. Physical restraint is not required where the arrestee voluntarily submits. Private security personnel may also effect arrests under §837 (citizen's arrest), and after a lawful private-person arrest must deliver the arrestee without unnecessary delay (§847). A written acknowledgment (d) is not required.

Penal Code §836(a) allows a peace officer to arrest on probable cause that a felony was committed, with significant protection from civil liability even if it later turns out no felony actually occurred. Penal Code §837(3), by contrast, requires that a felony 'has been in fact committed' — a mistake about whether any crime occurred can expose the private person to false-arrest liability (see Cervantez v. J.C. Penney Co.). This is the most consequential difference between peace-officer and private-person arrest authority. Tools (a, d) and reporting (c) are not the relevant statutory distinction.

Penal Code §837(1) authorizes a private-person arrest for a public offense 'committed or attempted in his presence.' A witness report of a misdemeanor that occurred outside the guard's actual perception does not satisfy that requirement. The guard may briefly detain to investigate or summon police; for a misdemeanor not in presence, the police make the arrest. A felony arrest under §837(2)-(3) follows a different rule — see the next question.

Penal Code §837(3) authorizes a private-person arrest 'when a felony has been in fact committed, and he has reasonable cause for believing the person arrested to have committed it.' Unlike misdemeanors (in-presence only under §837(1)), felonies may be arrested by private persons on reasonable cause. The reasonable-cause standard requires more than mere suspicion. After the arrest, the guard must deliver the arrestee to a peace officer or magistrate without unnecessary delay (§847).

The 'reasonable cause' (often called 'probable cause') standard from People v. Ingle (1960) 53 Cal.2d 407 is: a state of facts that would lead a person of ordinary care and prudence to believe and conscientiously entertain an honest and strong suspicion that the person arrested is guilty of a crime. This is far more than mere suspicion (a) but far less than the criminal-trial 'beyond a reasonable doubt' standard (b). Purely subjective belief without an objective factual basis (d) is insufficient and exposes the guard to false-arrest liability.

Penal Code §837(1) allows a private person to arrest for any public offense — including a felony — committed or attempted in his presence. Armed robbery is a felony (PC §§211, 212.5). Reasonable force consistent with §835's restraint authority is permitted, but tactical reality and officer-safety best practices weigh heavily here — most BSIS curricula advise against engaging armed suspects directly. After arrest, the guard must deliver the arrestee without unnecessary delay (§847). BSIS does not pre-authorize specific arrests (d).

Penal Code §837(3) requires both (1) that 'a felony has been in fact committed' AND (2) that the arrestor have reasonable cause to believe the arrestee committed it. If no felony was in fact committed — even with reasonable belief — the arrest fails to meet §837(3) and exposes the private person to false-arrest civil liability (Cervantez v. J.C. Penney Co. (1979) 24 Cal.3d 579). This is the key difference from peace-officer §836 authority, which generally protects officers acting on reasonable cause even if no crime occurred. Where §837(1) (in-presence) applies, it provides a surer authority.

Penal Code §847(a) requires a private person who has arrested another 'without unnecessary delay, take the person arrested before a magistrate, or deliver him or her to a peace officer.' Delay beyond what is reasonably necessary may invalidate the arrest and exposes the guard to false-imprisonment civil claims. Private security does not conduct interrogations (a), maintain custody indefinitely (c), or have authority to release based on apology (d) — those decisions belong to peace officers and the DA.

Penal Code §490.5(f)(2) gives merchants (and employees/agents, including security) a limited privilege to detain a person they have probable cause to believe unlawfully took merchandise. The detention must be in a reasonable manner and last no longer than reasonably necessary to investigate ownership and to await a peace officer. Excessive force (a), strip searches (c), and prosecutorial charging (d, which is the DA's role) exceed the privilege and expose the guard and merchant to civil liability for false imprisonment, battery, or civil-rights violations.

California recognizes three levels of encounter: (1) consensual contact — no restraint, no justification required; (2) detention — temporary restraint requiring reasonable suspicion of criminal activity; (3) arrest — full custody requiring reasonable/probable cause. A consensual approach where the person remains free to walk away is not a seizure (People v. Bennett (1998) 17 Cal.4th 373). Once a reasonable person would not feel free to leave, a detention has occurred and must be justified. A full arrest requires §837 authority. The Fourth Amendment applies most directly to government actors; private security operates within state-law constraints, primarily §490.5 and §837.

Penal Code §841 generally requires the person making an arrest — peace officer or private person — to inform the arrestee of the intention to arrest, the cause of the arrest, and the authority making it. Miranda warnings (b) apply to custodial interrogation by government actors and generally do not bind private security making a citizen's arrest. Written consent (d) is not required. Compliance with §841 supports the lawfulness of the arrest and protects against civil claims.

Penal Code §841 itself recognizes that notice need not be given when the person to be arrested is actually engaged in commission of an offense, is in flight after commission, or where giving notice would be impractical because of intended use of force by the suspect. The general rule is to give the notice; exceptions are narrow and fact-specific. Convenience (a) is not a basis; the duty is not absolute (b); and no court order is required (d).

A private person making a lawful arrest may use reasonable force necessary to effect and maintain the arrest, consistent with §835's restraint authority and common-law tort principles. Deadly force (a) is reserved for extremely narrow circumstances (defense of life) and exposes the guard to grave criminal and civil liability. Releasing on any resistance (c) would defeat arrest authority. The peace-officer use-of-force statute §835a (d) addresses peace officers specifically — its reasonable-force principles inform civil standards but private security does not enjoy peace-officer immunities.

A private security guard's authority to search incident to a citizen's arrest is narrower than a peace officer's. The recognized scope is a limited search for weapons (to secure the guard's safety) and to prevent destruction of evidence, pending transfer to a peace officer. Strip searches (c) and full inventory (a) exceed this authority and may constitute battery or unlawful search. Some search authority does exist (so 'never' (d) is wrong). Best practice: avoid all searches when possible, secure the area, and wait for police.

Trespass under §602 is a misdemeanor; if it occurred in the guard's presence, §837(1) authorizes a citizen's arrest. Best practice is to first issue a lawful warning to leave (often resolves the situation), then effect an arrest with reasonable restraint if the person refuses, and contact police promptly to comply with §847's 'without unnecessary delay' rule. Overwhelming force (a) is unlawful; broad searches (c) exceed limited-search authority; indefinite detention (d) violates §847 and exposes the guard to false-imprisonment liability.

Penal Code §490.5(f)(3) permits detention in a reasonable manner and for a reasonable time to investigate ownership, request that a peace officer take custody, and surrender the person to the officer. Excessive duration, humiliating treatment, or detention beyond reasonable investigative scope creates civil liability. Mandatory handcuffing (c) and location restrictions (d) are not statutory; 24-hour detention (a) is dramatically beyond what is reasonable and would constitute false imprisonment.

Penal Code §490.5(f)(2) requires the merchant or merchant's agent to have 'probable cause to believe the person to be detained was attempting to unlawfully take or has unlawfully taken merchandise from the premises.' Mere suspicion (a) is insufficient and exposes the guard to false-imprisonment liability. Video (c) and confession (d), while highly probative, are not the statutory threshold — probable cause can be established through other reliable observations.

BPC §7583.6 and the BSIS regulatory framework require any person performing security guard duties for compensation in California to be registered with BSIS and to complete mandated training. As of SB 652 (effective January 1, 2026), the 8-hour Power to Arrest and Appropriate Use of Force course must be administered and certified by a single BSIS-licensed training provider, and must be completed within 6 months before submitting the Guard Card application. A college degree (a), peace-officer sponsorship (c), and trade-association membership (d) are not BSIS requirements.

Penal Code §849(a) requires that when a person arrested without a warrant is delivered into custody, the arresting or receiving officer 'shall, without unnecessary delay, take the person arrested before the nearest or most accessible magistrate in the county in which the offense is triable.' This is the back-end counterpart to §847's delivery duty. The guard's report and testimony remain relevant (b is overbroad); booking timelines are governed by Penal Code §825 (48-hour rule, excluding Sundays/holidays), not 24 hours (d); release under §849(b) is discretionary, not automatic (a).

Penal Code §849(b) lists three statutory grounds for officer release: (1) insufficient grounds for a criminal complaint, (2) arrest for intoxication only with no further proceedings desirable, and (3) arrest for being under the influence of a controlled substance only, with delivery to a county treatment facility. A bare promise not to reoffend (a) is not a statutory ground and does not authorize release; that would be the role of a court or the District Attorney. An §849(b) release is treated as a detention and not an arrest for record purposes.

Penal Code §849.5 expressly provides that when a person is arrested and released under §849(b)(1), 'the arrest shall be deemed a detention only.' This protects the released person from carrying an arrest record where the officer concluded there was insufficient basis to proceed. Penal Code §851.6 reinforces this by requiring records to reflect a detention rather than an arrest. Options (b), (c), and (d) misstate the legal effect and would undermine the protective purpose of the statute.

Penal Code §836(c)(1) authorizes (and in some circumstances requires) a peace officer responding to a domestic violence call to make a warrantless misdemeanor arrest based on probable cause that DV occurred, even outside the officer's presence — an exception to the in-presence misdemeanor rule. This authority is specific to peace officers. Penal Code §13701 sets DV response policies for law enforcement agencies. Private security guards do not have §836(c) authority; the guard's role is to ensure safety, call police, and preserve evidence. Options (a)-(c) wrongly extend statutory peace-officer authority to private persons.

Violation of a domestic violence restraining order is a misdemeanor under PC §273.6 (and can be charged under §166(a)(4) as contempt). Because the violation is in the guard's presence, §837(1) supports a citizen's arrest using reasonable restraint, with §847 delivery to police. The priority is always immediate notification to law enforcement under §836(c)'s DV framework. Confiscating personal items (b) and unilateral release without report (c) are improper; the offense is generally a misdemeanor, not a felony absent special circumstances (a is mischaracterized).

The core procedural difference is the §837(3) 'in fact committed' requirement applied to private-person felony arrests, contrasted with the §836 probable-cause standard for peace officers. A peace officer acting reasonably is protected even if it later turns out no felony actually occurred; a private person is not. Both peace officers and private persons must give §841 notice (b is wrong). Deadly force authority is narrower, not broader, for private persons (c). Warrantless arrests are widely authorized for both categories under §§836 and 837 (d is wrong).

Battery under §242 is a misdemeanor; if committed in the guard's presence, §837(1) authorizes a private-person arrest. Section 836(c) (a) is the DV mandatory-arrest authority limited to peace officers. Section 835a (b) is the peace-officer use-of-force statute that does not itself confer arrest authority on private persons. Section 849 (c) governs what happens after the arrest, not the authority to make it. The guard should apply reasonable restraint, give §841 notice, and deliver the arrestee under §847.

Reasonable suspicion (for detention) and probable cause (for arrest) both require articulable facts indicating criminal activity (In re Tony C. (1978) 21 Cal.3d 888). Clothing, group association, or perceived affiliation without observed unlawful conduct does not, by itself, establish either standard. The guard may engage consensually, observe, document, and call police if conduct escalates, but cannot lawfully detain on appearance alone. Options (a), (c), and (d) misstate the law; arbitrary durations and owner consent do not cure constitutionally insufficient cause.

Theft of property over $950 may be charged as grand theft (PC §487), a wobbler that can be a felony. Because the offense occurred in the guard's presence, §837(1) authorizes a private-person arrest for the public offense — whether characterized as a misdemeanor or felony. The shopkeeper's privilege (PC §490.5) supplements this in retail contexts. Indefinite detention (d) violates §847; option (b) misstates the value threshold's effect on in-presence authority; option (a) wrongly denies citizen's-arrest authority for in-presence offenses.

Penal Code §835 states that the person arrested 'may be subjected to such restraint as is reasonable for his arrest and detention.' Reasonableness is judged objectively from the totality of circumstances and is independent of the arrestor's subjective intent (b). Options (c) and (d) describe escalation models that would routinely produce excessive force. The §835 standard applies to all arrestors, peace officer and private alike, although peace officers also have additional statutory protections under §835a and Graham v. Connor's objective reasonableness test.

A standard Guard Card permits unarmed security duty only. To carry a firearm on duty, a BSIS-registered guard must obtain a separate Firearms Permit under BPC §7583.12, which requires additional firearm-specific training (typically 14 hours), qualification at a BSIS-approved range, and a separate Department of Justice/FBI background check. Carrying without the permit may also implicate PC §25400 (carrying concealed weapon). Options (a)-(c) do not satisfy BPC §7583.12 and would leave the guard unauthorized to be armed on duty.

Business & Professions Code §7585.10 (and related BSIS regulations) requires a separate Baton Permit to carry a baton in performance of guard duties. The applicant must complete a BSIS-approved baton training course taught by a certified instructor. The permit is distinct from the basic Guard Card and from firearm or pepper-spray permits. Supervisor authorization (a) cannot substitute for the regulatory requirement; academic courses (c) and trade-association membership (d) are not BSIS-recognized credentials.

Penal Code §22810 permits adult civilians (with limited exceptions for felons, addicts, and minors) to possess OC for lawful self-defense, but commercial security use typically involves a state-certified training course. BSIS expects guards using OC on duty to demonstrate training. Option (a) overstates civilian freedom, since training is the practical norm for duty carry; option (b) confuses OC with firearms; option (c) wrongly limits OC to sworn officers. The substantive use rule remains reasonableness under §835 and applicable use-of-force principles.

Penal Code §830 enumerates the categories of peace officers; private security guards are not peace officers. Vehicle Code §2800 makes it a crime to disobey a peace officer's lawful order, presupposing the order comes from a peace officer. A Guard Card holder cannot lawfully conduct a vehicle stop, write traffic citations, or impose civil booting on a moving traffic violation alone. The guard may report to police, document plates, and request the vehicle leave private property. Options (b), (c), (d) all misstate or invent authority.

California does not have a general 'stop and identify' statute. Hiibel (a U.S. Supreme Court case from Nevada) upheld such statutes where they exist; California has not enacted one for general police encounters and certainly not for private security. A guard may request ID, but refusal alone is not a crime under §148 (which addresses obstruction/resistance of peace officers, not private persons) and does not by itself establish reasonable suspicion. Options (a), (b), (c) overstate guard authority and risk false-arrest liability.

Penal Code §853.6 allows a peace officer to release a person arrested for a misdemeanor on a written promise to appear, in lieu of taking the person before a magistrate. The authority is statutorily limited to peace officers. A private security guard who has made a citizen's arrest must deliver the arrestee to a peace officer or magistrate without unnecessary delay under §847; the guard cannot issue a citation, set bail, or release the arrestee on a promise to appear. Options (b)-(d) invent authority that does not exist for private persons.

Citizen's-arrest authority under §837 is not limited to private property — any public offense committed in the guard's presence may trigger §837(1) authority. However, the property owner's right to exclude under §602 applies to private property, not to public sidewalks where there is no trespass. The guard may not order pedestrians off a public right-of-way for mere presence. Options (a), (c), (d) misstate the public-private distinction and create false-arrest exposure if acted upon.

Penal Code §11165.7 enumerates mandated reporters — primarily teachers, healthcare practitioners, social workers, clergy, and certain other professionals. Security guards are not generally listed, although a guard's specific posting (e.g., at a school) may bring them within a covered role. Regardless of statutory status, guards should report suspected child abuse to law enforcement. Options (a), (b) overstate; option (d) wrongly substitutes private investigation for the law-enforcement role under §11166.

Civil Code §43.55 protects peace officers from civil liability for false arrest if they had reasonable cause to arrest and acted without malice. Penal Code §847(b) provides similar peace-officer protection. Private persons effecting citizen's arrests must comply with §837's stricter requirements — particularly the §837(3) 'in fact committed' rule — and have less robust statutory protection. Options (b), (c), (d) misstate the asymmetric immunity structure that distinguishes peace-officer from private-person liability.

BPC §7583.39 (and California vicarious-liability principles, including respondeat superior under Civil Code §2338 and case law) make the security licensee responsible for acts of employees within the scope of employment. A wrongful arrest, excessive force, or unlawful detention by a uniformed guard on duty creates direct exposure for the security company. This is why companies require training, policy compliance, and incident reports. Options (a)-(c) misstate scope-of-employment doctrine — written pre-authorization is not required and civil torts are within scope.

SB 652 amended the BSIS training scheme to require the 8-hour Power to Arrest and Appropriate Use of Force course be administered and certified by a single BSIS-licensed training provider. The legislative intent was to prevent fragmentation, ensure curriculum integrity, and produce a verifiable certificate of completion. Splitting across providers (a), pure-online delivery without the in-person component (c), and self-certification (d) are inconsistent with the SB 652 framework and BSIS implementing guidance.

SB 652 imposes a 6-month freshness requirement: the 8-hour Power to Arrest and Appropriate Use of Force course must be completed within 6 months before the Guard Card application is submitted to BSIS. The window is designed to ensure the applicant's training is current. 16 CCR §628 sets the exam-pass requirement at 100% with retakes permitted. Options (a), (b), and (c) misstate the SB 652 window and would render the application non-compliant.

16 CCR §628 requires a 100% score on the Power to Arrest and Appropriate Use of Force course final exam. Retakes are permitted — applicants who do not pass on the first attempt may retake until they pass. The high bar reflects the gravity of the subject matter: errors about arrest authority and use of force have direct consequences for citizens' liberty and safety. Discretionary or lower passing standards (a), (c), (d) misstate the regulation; instructors administer but cannot waive the 100% requirement.

Penal Code §836(a) authorizes peace officers to arrest without a warrant: (1) for a public offense committed or attempted in the officer's presence, (2) on probable cause that the person committed a felony (regardless of presence), and (3) on probable cause for certain misdemeanors with statutory specification. This authority is broader than the §837 private-person framework. Geographic (a), supervisory (b), and time-of-day (d) restrictions are not §836's text. Warrant requirements (§1535) apply only when no warrantless authority exists.

Penal Code §149 makes it a public-offense crime for a peace officer to assault or beat a person under color of authority without lawful necessity. Punishment ranges depending on injury; great-bodily-injury cases can trigger felony exposure (with state-prison sentencing options). The statute supplements, rather than replaces, civil remedies and POST/internal discipline. Options (b), (c), (d) understate the criminal exposure. The principle informs private-security training because excessive force can also expose guards to assault (§240) and battery (§242) charges.

Penal Code §834 defines an arrest as 'the taking of a person into custody, in a case and in the manner authorized by law.' It may be made by a peace officer or by a private person under the relevant authority statutes. The mechanical 'how' is then specified in §835 (actual restraint or submission to custody). Court appearances (a), booking (b), and filing a complaint (c) are post-arrest events. Together §§834-835 form the foundational arrest framework on which §836 (peace officer) and §837 (private person) build.

Penal Code §834a expressly states that if a person has knowledge, or by exercise of reasonable care should have knowledge, that they are being arrested by a peace officer, 'it is the duty of such person to refrain from using force or any weapon to resist such arrest.' The statute applies to peace-officer arrests; common-law rules historically allowed reasonable resistance to plainly unlawful arrests, but §834a sharply curtails that for peace-officer arrests. Options (a), (c), (d) describe the historic rule or invent permissions inconsistent with §834a.

Penal Code §148(a)(1) makes it a misdemeanor to willfully resist, delay, or obstruct a peace officer (or EMT) in the discharge of duty, punishable by up to one year in county jail and/or fine. The offense covers a broad spectrum of conduct. Crucially, §148 by its terms protects peace officers — not private security guards — so resistance to a private guard's lawful citizen's arrest is generally addressed through battery (§242), assault (§240), or related statutes, not §148. Options (a), (b), (c) misstate the classification.

Penal Code §847 requires delivery to a peace officer or magistrate 'without unnecessary delay.' Unreasonable delay can invalidate an otherwise lawful citizen's arrest and supports false-imprisonment civil claims (Civil Code §43.55's protection against false-arrest claims applies primarily to peace officers; private persons depend on §837 compliance). PC §148 (c) addresses obstruction of peace officers, not delay by an arresting private person. Options (b), (d) understate the legal exposure; BSIS may also impose discipline.

BPC §7582.1 defines 'private patrol operator' and related security activities; §7583.6 imposes the registration and training requirements. The scope of duty is protection of persons and property — observe, deter, report, and detain or arrest only within the private-person framework (PC §§835-847, §490.5). Peace-officer powers (a) are statutorily separate. Investigative-licensing (b) belongs to PIs (PC §7521). Citations and warrants (c) are peace-officer functions. Armed duty requires additional permits (BPC §§7583.12, 7585.10).
