2026-11-1501Is a hyeongsa different from a police officer?
Hyeongsa is the common term for police officers who handle criminal investigations, so it describes their job, not their rank. Dramas often show them working in plain clothes rather than uniforms while looking into cases. You can think of them as officers whose role differs from those on patrol or traffic duty.
02What are the police ranks in Korea?
Korean police have 11 ranks. From the bottom they are sungyeong, gyeongjang, gyeongsa, gyeongwi, gyeonggam, gyeongjeong, chonggyeong, gyeongmugwan, chian-gam, chian-jeonggam and chian-chonggam. The Commissioner General of the Korean National Police Agency holds the top rank. In dramas, characters often address each other by rank.
03Are team leader and banjang ranks?
No. Team leader and banjang are positions for someone who leads an investigation team, not ranks. Two team leaders may hold different ranks depending on their department. Dramas often use banjang affectionately, but actual unit names and titles vary by period and department.
04What is a gangnyeokban?
Gangnyeokban is the common name for the unit that investigates violent crimes such as murder, robbery and assault. Officially, such units are now often called violent crimes teams. In crime dramas, this is where the detective protagonists are most often assigned.
05What is a metropolitan investigation unit?
A gwangyeok susadae is an investigation unit under a provincial or metropolitan police agency that handles crimes spanning several areas or large-scale cases. Dramas show these units tackling organized crime or serial cases too big for a single police station. Names and structures can differ between regional police agencies.
06What is the NFS in crime dramas?
Gukgwasu is short for the National Forensic Service, the state agency that carries out scientific examinations such as autopsies, DNA analysis and toxicology tests. It was established in 1955. In dramas, detectives often get a crucial clue when they hear that the forensic results are in.
07What does a forensic science unit do?
A police forensic science unit searches crime scenes for evidence such as fingerprints, blood traces, footprints and hair, then documents and collects it. The evidence is sent to analysis agencies for examination. In dramas, they are the people in white protective suits carefully examining a scene.
08Does Korea have criminal profilers?
Yes. Korean police have criminal analysts, or profilers, who support investigations by studying offenders' behavior and psychology. They are generally said to have been introduced in earnest in the early 2000s. In dramas, they often appear guiding an investigation by inferring what kind of person the culprit is.
09What is the difference between a suspect, a pisuija and a defendant?
Yonguija is a broad term for someone suspected of a crime, while piuija refers to a person formally under investigation by authorities. Once a prosecutor indicts that person, they are called a pigoin, or defendant. That is why dramas change the term as a case moves forward.
10Who is a chamgoin in crime dramas?
A chamgoin is not someone accused of a crime but a person who comes to investigators to give a statement about what they know of a case. Witnesses or people close to a victim may be questioned in this role. Dramas sometimes use the twist of a chamgoin turning into a suspect during questioning.
11What is an emergency arrest?
An emergency arrest lets investigators detain someone without a warrant when the suspected crime is serious and there is no time to get a judge's approval. To keep holding the person, they must request a detention warrant within 48 hours; otherwise the person must be released. Many race-against-time scenes in dramas come from this rule.
12Can police conduct a search and seizure anytime?
No. As a rule, a search and seizure requires a warrant issued by a court, which specifies the places to be searched and items to be seized. That is why dramas show detectives anxiously waiting for a warrant. Exceptions exist but are defined by law.
13Is there a statute of limitations for murder in Korea?
Currently, there is no statute of limitations for murder in Korea. It was abolished by a 2015 revision of the Criminal Procedure Act, commonly known as the Taewan Act. Before that, cases that could no longer be prosecuted because time had run out sometimes became material for dramas.
14What is a long-term unsolved case?
A long-term unsolved case, or cold case, is one in which the culprit has not been found for many years. After the statute of limitations for murder was abolished in 2015, dedicated teams were reportedly set up to reinvestigate such cases. Some dramas, like tvN's Signal, are built around unsolved cases.
15What do jambok and tammun mean?
Jambok means a stakeout, in which detectives hide and watch a place where a suspect may appear, often for hours. Tammun means canvassing, going around asking people nearby for information. Detectives eating cup noodles in a car during an all-night stakeout is a classic drama scene, and both are basic investigative methods.
16What is a montage in crime dramas?
In Korean, montage means a composite sketch: a drawing or assembled image of a suspect's face based on a witness's memory. It is released on wanted posters or through the media to gather tips. Recent dramas sometimes show faces being built with computer software.
17What is black box footage in dramas?
In Korea, a black box means a dashboard camera installed in a car to record what happens around it while driving. Because many vehicles have one, the footage is often used as evidence in accidents and crimes, along with street CCTV. Dramas frequently show detectives hunting for black box recordings.
18What number do you call for the police in Korea?
In Korea, call 112 to report a crime to the police, and 119 for fires or medical emergencies. Dramas often show characters in danger dialing 112. If you need help while traveling, do not hesitate to call the appropriate number.
19What cases does a cyber investigation unit handle?
A cyber investigation unit is a police team that tackles crimes using the internet and telecommunications, such as hacking, online fraud, personal data leaks and voice phishing scams. Recent dramas increasingly show detectives tracing digital evidence. If you suspect you have been targeted, report it to the police right away.
20Are crime drama scenes realistic?
Dramas often shorten or exaggerate investigative procedures for dramatic effect. Things like how warrants are issued, how questioning works and how long evidence analysis takes may differ from reality. Do not apply legal knowledge from dramas directly to real situations, and consult professionals or official agencies when needed.
