Penology Officer Exam cheat sheet

Mala in se crimes are inherently wrong (murder, theft); mala prohibita acts are wrong only because a statute forbids them (illegal gambling, jaywalking).

Felonies under the Revised Penal Code are classified by degree of participation (principal, accomplice, accessory) and by gravity (grave, less grave, light), which drive penalty ranges.

Article 4 of the Revised Penal Code: criminal liability attaches for a felony committed by fault (culpa) even if the wrongful act differs from what was intended.

Mistake of fact negates criminal intent when the mistake is honest and reasonable; mistake of law generally does not excuse.

Conspiracy exists when two or more persons agree to commit a felony and decide to act on it; conspiracy is not a crime itself except where the law specifically punishes it.

Justifying circumstances (self-defense, defense of stranger, state of necessity, lawful exercise of right) mean no crime and no civil liability, except civil liability in state of necessity.

Exempting circumstances (imbecility, minority, accident, compulsion of irresistible force) remove criminal liability but may leave civil liability.

Prescription periods for crimes depend on the penalty imposed; light penalties prescribe in months, grave penalties in years, and the period is interrupted by filing of the information.

The Bureau of Corrections administers national prisons (New Bilibid Prison, Correctional Institution for Women, Davao Prison and Penal Farm, Iwahig, Sablayan, Leyte Regional Prison).

Jails are generally managed by BJMP in cities and municipalities and by provincial governments for provincial jails; the Bureau of Jail Management and Penology is under the DILG.

Purposes of punishment: retribution, deterrence, incapacitation, rehabilitation, and restoration (restorative justice).

The penitentiary system evolved from congregate (Auburn) to separate (Pennsylvania) models; the Irish system and Maconochie's mark system introduced progressive stages and tickets of leave.

The indeterminate sentence law fixes a minimum and maximum term; the Board of Pardons and Parole decides parole eligibility after the minimum is served.

The Philippine prison system historically used the Walnut Street and Eastern State Penitentiary models as reference points, but the modern system emphasizes reformation under the Bureau of Corrections.

Restorative justice focuses on repairing harm through victim-offender mediation, restitution, and community participation rather than purely punitive measures.

Chain of custody requires documenting every transfer of evidence: who collected it, when, where, and to whom it was released, with signatures.

Fingerprint identification uses Galton-Henry classification; the three types of latent prints are visible, plastic, and latent (invisible).

DNA profiling compares short tandem repeats (STRs); a match probability is expressed statistically, and a partial profile has limited probative value.

Ballistics examines firearm, bullet, and cartridge case markings: rifling grooves on bullets, firing pin and breech face marks on cartridge cases.

Questioned document examination compares handwriting, ink, paper, and printing; exemplars must be collected under comparable conditions.

Forensic toxicology screens for drugs and poisons in blood, urine, and tissue; alcohol is commonly measured by breath or blood with legal thresholds set by statute.

Serology identifies body fluids by presumptive and confirmatory tests; blood typing and DNA analysis follow presumptive screening.

Forensic pathology determines cause, manner, and time of death; livor, rigor, and algor mortis are used together, not individually, to estimate postmortem interval.

Police organization follows the principle of unity of command and span of control; line and staff functions are distinct.

The PNP's powers derive from RA 6975 as amended by RA 8551, which also created the National Police Commission and the People's Law Enforcement Board (PLEB).

The police patrol function is the backbone of police operations; patrol covers prevention, deterrence, and community contact.

Police operational planning uses the acronym SAP (situation, mission, execution, administration, command and signal) and the estimate of the situation process.

Use of force follows the escalation-of-force continuum: presence, verbal direction, empty-hand control, less-lethal weapons, then lethal force only when justified.

The Miranda doctrine applies to custodial interrogation: the suspect must be informed of the right to remain silent and to counsel before any waiver.

Compulsory arbitration and the Napolcom handle administrative complaints against PNP members; PLEB handles citizen complaints in cities and municipalities.

The five Ws and one H (who, what, when, where, why, how) structure the initial investigation report and the case theory.

The three tools of investigation are information, interview/interrogation, and instrumentation (forensic science).

The cardinal points of investigation: identify the victim, identify the suspect, determine the time and place, and determine the motive and method.

Interviewing witnesses follows a funnel from free narrative to specific questions; leading questions are avoided in the free narrative stage.

Crime scene processing follows the sequence: secure the scene, document (photograph, sketch), search, collect and preserve evidence, and release the scene.

Modus operandi describes the offender's method; it is distinct from signature, which is a psychological need of the offender.

The chain of custody and the exclusionary rule interact: illegally obtained evidence is inadmissible, and unbroken custody is required for admissibility.

Entrapment is the inducement of an otherwise innocent person; it is a defense, while instigation by law enforcers is not.

The Universal Declaration of Human Rights (1948) and the International Covenant on Civil and Political Rights protect life, liberty, fair trial, and freedom from torture.

The Philippine Constitution's Bill of Rights: right to life, liberty, property, due process, equal protection, and freedom from unreasonable searches and seizures.

Reading comprehension: main idea, supporting details, inference, and tone are distinct question types; the main idea is not a detail.

Basic math: percentage = (part/whole) x 100; rate = distance/time; simple interest = principal x rate x time.

Logic: a valid syllogism requires a distributed middle term; affirming the consequent and denying the antecedent are invalid forms.

Vocabulary in context: use surrounding sentences and word roots to infer meaning rather than relying on a single familiar sense.

Report writing: chronological or logical order, factual tone, and clear attribution of statements are core requirements of official correspondence.
