The exam draws 30 questions from a bank of 58. You have 45 minutes, and you need 80% to pass. Questions apply the law to situations. To prepare, read this guide alongside the cited sections of the San Andreas codes, the 2026 Law Enforcement Reform Package and the federal authorities below. The U.S. Constitution binds every San Andreas officer. Supreme Court decisions are binding; federal circuit decisions are accepted authority, and where circuits differ the academy teaches the rule that protects rights more.
The Fifth Amendment says no person shall be compelled to be a witness against himself (U.S. Const. amend. V). Miranda v. Arizona held that statements from custodial interrogation are inadmissible unless the suspect was warned of the rights to silence and counsel and waived them, and Miranda is a constitutional rule that legislation cannot overrule (Dickerson v. United States). The warnings tell the suspect that he has the right to remain silent, that anything he says can be used against him in court, that he has the right to have a lawyer present during questioning, and that a lawyer will be appointed if he cannot afford one. Two conditions trigger them, and both must exist: custody and interrogation. Without custody, as in a voluntary interview, no warnings are required. Without interrogation, as when a handcuffed arrestee blurts out a statement no one asked for, no warnings are required either. Warnings are not a ritual for every contact; they are a precondition for using the answers to custodial questioning. Give them from an approved card in plain words, record that you did, and record the suspect's answer in his own words.
Custody means formal arrest or restraint on freedom of movement to the degree associated with formal arrest. It is objective: the question is how a reasonable person in the suspect's position would understand the situation, and an officer's undisclosed suspicions do not decide it (Stansbury v. California). Ordinary traffic stops are not custody, but a motorist placed in custody must be warned regardless of the offense (Berkemer v. McCarty). Questioning at the station is not custody when the person came voluntarily, was told he was not under arrest and left afterwards (Oregon v. Mathiason). Questioning a prisoner apart from the general population is not automatically custody (Howes v. Fields); the question is whether the interview itself added restraints a reasonable inmate would see as arrest-like. A child's age, when known or objectively apparent, is part of the analysis (J.D.B. v. North Carolina). Factors include where the questioning happens, how long it lasts, how many officers are present, whether the person is told he is free to leave, whether he is restrained, and whether he is allowed to leave at the end. Separately, the Fourth Amendment forbids taking a person to the station for interrogation without consent unless there is probable cause (Dunaway v. New York; Kaupp v. Texas).
Interrogation includes express questioning and any words or actions police should know are reasonably likely to elicit an incriminating response (Rhode Island v. Innis). A speech to a partner, delivered within the suspect's hearing and designed to make him talk, can be interrogation; a neutral remark that officers had no reason to think would prompt a confession is not. Volunteered statements are not the product of interrogation and are admissible, but follow-up questions about them are interrogation. Two settings carry special rules. An undercover officer posing as a cellmate need not give warnings, because a suspect speaking to someone he believes is a fellow inmate faces no police-dominated pressure (Illinois v. Perkins), although once the suspect has been charged the Sixth Amendment changes that answer. Questions necessary to address an immediate threat to public safety, such as where a discarded gun is, may be asked before warnings (New York v. Quarles). The public-safety exception is narrow: it covers questions aimed at the danger, such as 'Where is the gun?', not questions aimed at building the case, such as 'Why did you shoot him?'. When the danger is resolved, give warnings before investigative questioning.
A waiver must be knowing, intelligent and voluntary. It need not be express; it can be inferred from words and conduct (North Carolina v. Butler). A suspect who has received and understood the warnings and then makes a knowing statement can be found to have impliedly waived (Berghuis v. Thompkins). A valid waiver is not undone because police did not tell the suspect a lawyer was trying to reach him (Moran v. Burbine). A juvenile's waiver is judged on the totality of the circumstances, including age, experience, education and intelligence (Fare v. Michael C.). Good practice still matters, because the prosecution must prove the waiver: read the warnings from the card, ask whether the suspect understands each right, ask whether he is willing to talk, and record the whole exchange on body camera or interview-room video. A clear record of understanding defeats later claims of confusion. Never tell a suspect that the warnings are a formality, that talking cannot hurt him, or that a lawyer will only slow things down; misstating the rights undermines the waiver and the case.
A suspect must invoke the right to silence unambiguously; merely staying silent for a long time is not an invocation, and a knowing answer after warnings can be an implied waiver (Berghuis v. Thompkins). Once a suspect does invoke silence, it must be scrupulously honored; questioning may resume only after a significant pause, fresh warnings and a different subject (Michigan v. Mosley). Silence has other limits as evidence. A defendant's silence after Miranda warnings cannot be used to impeach him (Doyle v. Ohio), so a report should never characterise post-warning silence as a sign of guilt. Outside custody the rule is different: a person in a voluntary, non-custodial interview who wants the privilege's protection must expressly invoke it (Salinas v. Texas). That rule concerns what a court may later admit; it does not change how you treat the person. Whether in or out of custody, record precisely what the person said, including 'I don't want to talk about that', and do not paraphrase an invocation into something weaker.
Once a suspect in custody asks for counsel, police may not interrogate further until counsel is present unless the suspect himself initiates further communication (Edwards v. Arizona). The request must be unambiguous; officers need not stop for an equivocal statement such as 'maybe I should talk to a lawyer' (Davis v. United States, 512 U.S. 452 (1994)). The academy's practice is to ask one neutral clarifying question, such as 'Are you asking for a lawyer now?', and to stop at once if the answer is yes. A clear request such as 'I want a lawyer' ends questioning; do not keep talking in the hope he will change his mind, and do not send a different detective to try. Initiation means the suspect, not the officer, starts a conversation about the investigation; a request for water or to use the bathroom is not initiation. If he does initiate, give fresh warnings and obtain a waiver before questioning. The Edwards bar ends after a 14-day break in Miranda custody (Maryland v. Shatzer); a short release and re-arrest the next day does not lift it. Record the request word for word and the time it was made.
Warnings must come before custodial questioning, not after a confession. A deliberate question-first, warn-later technique makes the warned repeat confession inadmissible (Missouri v. Seibert). Where an officer's failure to warn was a good-faith mistake and the first statement was voluntary, a later warned, voluntary confession is not automatically barred (Oregon v. Elstad), but relying on that rule is a gamble with the case. Remedies matter for officers' understanding. The remedy for a Miranda violation is suppression of the statement, and a Miranda violation alone is not grounds for a § 1983 suit (Vega v. Tekoh). That does not make Miranda optional: a suppressed confession can lose a homicide case, and coercion that makes a statement involuntary is a separate due process violation that can bring civil and criminal liability. A related rule protects officers themselves: statements compelled from an officer under threat of dismissal cannot be used against that officer in a criminal case (Garrity v. New Jersey). Internal-affairs interviews and criminal investigations of an officer must therefore be kept apart.
Separately from Miranda, the Fourteenth Amendment's due process clause forbids using involuntary statements. A confession is involuntary under due process only if coercive police activity produced it (Colorado v. Connelly); a suspect's own mental illness or a voice in his head, without police coercion, does not make it involuntary, though it may make it unreliable. Coercion includes violence or threats of violence, threats against family, promises of leniency or release in exchange for a confession, deprivation of sleep, food, water, medication or the bathroom, and questioning so prolonged that the will is overborne. Police misrepresentation, such as falsely saying an accomplice confessed, does not by itself make a confession involuntary (Frazier v. Cupp), but the academy discourages invented-evidence tactics, especially with juveniles and vulnerable suspects, because they raise the risk of false confessions. Prosecutors decide charges, so an officer may truthfully say he will tell the prosecutor the suspect cooperated, but must never promise a charge, a sentence or release. Coercing a statement also exposes the officer to Official Oppression (SAPC §38.74) and Deprivation of Civil Rights (§38.82).
The Sixth Amendment guarantees the accused the assistance of counsel (U.S. Const. amend. VI), and an indigent defendant charged with a serious crime is entitled to appointed counsel (Gideon v. Wainwright). The right attaches when formal charges are filed. After charges are filed, police may not deliberately elicit statements from the accused without counsel (Massiah v. United States). This is why a jailhouse informant placed to draw out a charged defendant about the charged crime violates the Sixth Amendment even though, before charges, an undercover cellmate needs no Miranda warnings (Illinois v. Perkins). Police may approach a charged defendant for questioning, and a valid Miranda waiver also waives the Sixth Amendment right (Montejo v. Louisiana); but if the defendant has invoked counsel in custody, Edwards still bars police-initiated interrogation. Check JusticeLink before any interview to learn whether the person has been charged, has a pending case or is represented, and record what you found. A statement obtained in violation of the right to counsel can be suppressed and can jeopardise the whole prosecution.
A child or minor is anyone younger than 18 (SAPC §1.37). Juveniles in delinquency proceedings are entitled to notice, counsel, confrontation and the privilege against self-incrimination (In re Gault). A child's age, when known or objectively apparent, is part of the custody analysis (J.D.B. v. North Carolina): a thirteen-year-old pulled from class into a closed room with an officer and a school administrator may be in custody where an adult would not be. A juvenile's request to see a probation officer is not an invocation of the right to counsel, and a juvenile's waiver is judged on the totality of the circumstances (Fare v. Michael C.). Juveniles are more suggestible, more eager to please authority and more likely to confess falsely to end an uncomfortable situation. Good practice is to notify a parent or guardian promptly, use simple language and ask the child to explain the warnings back in his own words, keep the interview short, avoid deception and promises entirely, record it in full, and allow a parent or attorney to be present where policy provides. Remember that juvenile cases are handled by the juvenile court, and that runaway status (SAFC §51.01) is a civil welfare matter, not a crime to be interrogated about.
Eyewitness identification is powerful and often wrong. Due process screens identifications only where police arranged suggestive circumstances (Perry v. New Hampshire); a suggestive situation that police did not create is left to cross-examination and the jury. When police do use a suggestive procedure, reliability is the linchpin in deciding admissibility (Manson v. Brathwaite), judged by the witness's opportunity to view, degree of attention, accuracy of the prior description, level of certainty and the time elapsed between the crime and the identification (Neil v. Biggers). A single-suspect show-up is suggestive and is justified only by necessity under the totality of the circumstances (Stovall v. Denno); the necessity is usually a fresh crime and a nearby suspect who must be confirmed or released quickly. A show-up should therefore be done promptly, near the scene, with the suspect presented in a way that does not suggest guilt where safety allows, and with the witness told that the person may or may not be involved. Never show a witness a single photograph of the suspect, and never tell a witness 'we caught him'.
A photo array or lineup should follow procedures that protect the witness's memory. Obtain and record the witness's description before any procedure. Include one suspect only, with fillers who fit the description the witness gave, so that the suspect does not stand out. Where possible, the procedure is administered blind, by someone who does not know which person is the suspect. Before viewing, tell the witness that the person may or may not be present, that he should not feel compelled to choose anyone, and that the investigation will continue either way. Record the witness's confidence in his own words immediately after any choice, before any feedback; never say 'good job' or 'that's our guy', because confirming feedback inflates confidence that the jury will later hear. Show multiple witnesses the array separately, and do not let them compare notes. Avoid repeating a procedure with the same suspect for the same witness, because a second viewing tests memory of the first procedure rather than of the crime. Record the whole procedure, keep the array exactly as shown, and document a non-identification or a filler pick as carefully as a suspect pick: both are evidence the defence is entitled to.
Interviewing victims and witnesses is a skill, not a formality. Address safety and medical needs first and separate witnesses before you interview them. Build rapport, explain who you are and why you are asking, and let the person give a free narrative with an open prompt such as 'Tell me everything that happened, from the beginning'. Do not interrupt; take notes, then go back to specific points with open questions ('Describe the man you saw') before narrower ones. Avoid leading or forced-choice questions ('Was the car red?', 'Was he tall or short?'), which plant details. Trauma often produces fragmented, non-linear memory; gaps and inconsistencies are not by themselves evidence of lying, so record them without judgment and allow breaks. Use a qualified interpreter where needed, not a child, a relative involved in the incident or the suspect. Quote key statements word for word, note demeanour and the time, and ask 'Is there anything else I should know?' before you finish. A person lawfully detained as a witness must give his name, date of birth and address (SAPC §38.17), and anyone who threatens a witness to change testimony commits Witness Intimidation (§38.21).
False confessions happen, and they are most likely when a vulnerable person meets a long, high-pressure interrogation. Risk factors include youth, intellectual disability, mental illness, intoxication or withdrawal, fatigue, isolation, lengthy questioning, threats or promises, and the officer's own certainty that the suspect is guilty. The most damaging error is contamination: feeding the suspect details of the crime through questions, photographs or the scene, so that a later confession appears to contain knowledge only the offender could have. Protect the investigation by recording the entire interview, from the first contact and the warnings to the end, rather than only the final statement; by withholding key facts (holdback details) and noting whether the suspect supplies them unprompted; by asking open questions that require the suspect to tell you what happened; and by corroborating every admission with independent evidence. Document breaks, food, water and medication. If a confession does not fit the physical evidence, it is a warning sign, not a detail to smooth over in the report. An accurate confession survives this scrutiny; a false one does not, and catching it protects both an innocent person and the case against the real offender.
