CLE (Criminology) common mistakes
CLE (Criminology) · Understand the traps and how to avoid them.
Treating the 1987 Constitution's Bill of Rights as the only source of criminal procedure rules, so the candidate answers arrest, search, and custody questions from memory of the Constitution alone and ignores Rule 113 and Rule 126 of the Rules of Court.
Reviewers often memorize constitutional provisions because they are short and quotable, then never drill the procedural rules that supply the operative requirements (warrantless arrest grounds, search warrant requisites, chain of custody timing). Exam items are usually built from the rules, not the constitutional text.
What to do instead
Build a two-column table for each procedure (arrest, search, seizure, inquest, bail). Left column: constitutional provision. Right column: the exact rule and section implementing it. Recite the rule section from memory, then state which constitutional clause it enforces. Do this for Rule 113 sections 5 and 6, Rule 126 sections 2, 3, 4, 10, and 13, and Rule 112 inquest provisions.
Answering warrantless search items with a blanket rule ('warrantless searches are invalid') instead of identifying which recognized exception applies and whether its specific limits were observed.
Candidates learn the exceptions as a list of names but never learn the conditions attached to each, so under time pressure they default to the general rule and pick the answer that sounds most rights-protective.
What to do instead
For each exception (incident to lawful arrest, plain view, consent, stop-and-frisk, vehicle, exigent circumstances, customs, checkpoints), write three lines: trigger, scope limit, and the leading fact pattern that tests it. Example: search incident to arrest covers the person and the area within immediate control, not a locked drawer in another room. Then answer ten fact patterns per exception and justify the scope limit, not just the exception name.
Confusing the three pillars of the criminal justice system with the five pillars, or listing agencies under the wrong pillar, when answering administration and system-flow items.
Older review materials use a five-pillar model (law enforcement, prosecution, courts, corrections, community) while current Philippine materials often present a three-pillar or six-pillar version. Candidates mix versions and lose items that test the flow of a case from arrest to release.
What to do instead
Adopt one model and anchor it to the case flow: law enforcement (arrest, investigation), prosecution (inquest, preliminary investigation, information), courts (arraignment, trial, judgment), corrections (commitment, incarceration, parole), community (reintegration, diversion). For each pillar, memorize the agency, the document it produces, and the next pillar it hands off to. State the model version explicitly in your notes so you do not blend versions.
Applying the plain view doctrine without checking all of its requisites, especially the requirement that the officer be lawfully in the position from which the view occurred and that the item's incriminating character be immediately apparent.
The doctrine is taught as a slogan ('if you can see it, you can seize it'), so candidates skip the lawful-position and immediately-apparent elements and choose answers that validate seizures made during an unlawful intrusion.
What to do instead
Memorize the requisites as a checklist: prior lawful intrusion, inadvertence (where the prevailing doctrine requires it), plain view of the item, and immediately apparent incriminating character. Then run five hypotheticals where one requisite fails and confirm the seizure is invalid. Practice stating which requisite is missing in each.
Mixing up the stages of criminal investigation, treating interrogation, interview, and custodial investigation as interchangeable, and missing the point at which constitutional safeguards attach.
Field terminology overlaps and reviewers use the words loosely. Candidates then fail items asking when Miranda-type warnings are required or whether a confession taken during a routine interview is admissible.
What to do instead
Define each term precisely in a glossary: interview (non-custodial questioning of witnesses or complainants), interrogation (questioning of a suspect), custodial investigation (questioning after custody or after the investigation focuses on the person). Attach the safeguard to the stage: custody plus interrogation triggers the warnings and the right to counsel. Then classify ten scenarios by stage before answering admissibility.
Skipping the elements of the offense when answering crime detection items, so the candidate identifies a suspect's act but cannot say which crime was committed or which elements remain unproven.
Candidates study investigation techniques (sketching, interviewing, evidence collection) in isolation from substantive law and never connect the facts gathered to the elements that must be established.
What to do instead
For each major offense in the syllabus, write the elements as a numbered list and beside each element note the evidence that proves it. When working a case-based item, tick elements one by one and name the missing element. This converts vague 'who did it' answers into element-driven conclusions.
Confusing the roles of crime prevention, crime suppression, and crime control, and answering prevention-program items with suppression measures such as patrol saturation or checkpoints.
The terms are used interchangeably in ordinary speech, and candidates memorize program names without classifying them by objective (prevent occurrence, interrupt commission, or manage after the fact).
What to do instead
Classify every program by objective before answering. Prevention: reducing opportunity before a crime occurs (environmental design, awareness campaigns, youth diversion). Suppression: interrupting an ongoing or imminent offense (patrol, checkpoints, buy-bust). Control: managing known offenders and cases after the fact. Build a three-column list of at least fifteen Philippine programs and place each one.
Treating research designs and sampling methods as vocabulary to be recognized rather than applied, so candidates mislabel a study design or choose a sampling method that cannot support the stated objective.
Reviewers drill definitions but not the decision rule for choosing a design or sample. Items that describe a study and ask for the appropriate design or the main threat to validity defeat memorized definitions.
What to do instead
Write a decision tree. Start with the question: describe, compare groups, or test cause? That selects descriptive, correlational, or experimental design. Then ask whether randomization was possible; if not, the design is quasi-experimental. For sampling, ask whether a sampling frame exists; if not, non-probability methods apply. Practice by reading ten short abstracts and labeling design, sample, and main validity threat.
Answering correctional items by mixing the Philippine correctional pillars, so the candidate places a convict in the wrong facility or applies the wrong release mechanism (parole versus probation versus pardon).
The correctional system is split across the Bureau of Corrections, provincial and city jails, the Bureau of Jail Management and Penology, and juvenile facilities, and release mechanisms come from different legal sources. Candidates memorize the names but not the jurisdiction or the legal basis.
What to do instead
Build a jurisdiction table: agency, population handled (convicted versus detained, sentenced versus awaiting trial, adult versus juvenile), legal basis, and release mechanisms available. Then write one paragraph each distinguishing probation (court-granted, after conviction, sentence suspended), parole (board-granted, after minimum term served), and pardon (executive). Answer ten placement and release items using only the table.
Describing forensic procedures in general terms instead of stating the specific preservation, packaging, and chain-of-custody requirements, so the candidate cannot identify the point at which evidence integrity was broken.
Candidates learn that chain of custody matters but never memorize the concrete links (who collected, who received, when, where, in what condition) or the packaging rules for different evidence types. Items that describe a break in the chain then look indistinguishable from compliant handling.
What to do instead
Write a chain-of-custody template with the required entries and memorize packaging rules by evidence type (biological evidence dried and breathable, wet evidence not sealed in plastic, sharp items in rigid containers, each item separately labeled). Then read five fact patterns and mark the exact link where integrity fails. Also memorize the statutory timing requirements for submitting seized drug evidence for laboratory examination.
Answering professional conduct items by choosing the most morally appealing option rather than the option that matches the specific ethical standard or administrative rule, such as the exact grounds for administrative liability or the correct procedure for filing a complaint against an officer.
Ethics items are worded so that several options sound virtuous. Candidates who have not memorized the operative standards (the code of conduct for public officials, the police professional standards, and the rules on administrative discipline) select by intuition.
What to do instead
Memorize the operative standards as short numbered lists: the norms of conduct for public officials, the grounds for administrative offenses, and the procedural steps for filing and hearing a complaint. For each practice item, name the specific standard the option violates or satisfies before choosing. Reject any option you cannot tie to a named standard.
