Brooklyn Nine-Nine Police Vocabulary: Precinct, Perp and Other Terms
Police shows can make five different words sound like they all mean “bad guy” and another five sound like they all mean “caught.” They do not.
The fastest way to untangle Brooklyn Nine-Nine police English is to ask what kind of information each word gives you: Place → Person → Status → Action.
PLACE — Where is police work happening?
PERSON — What role or label is being used for someone?
STATUS — Are they free, detained, convicted, or otherwise described by a current legal/police state?
ACTION — What are officers, investigators, lawyers, or witnesses doing?
PLACE: precinct is not the same thing as a holding cell
dog haunts the precinct ♪
Precinct is a core U.S. police-show word. It can refer to a local police district, and in everyday crime-show speech it often also points to the station serving that district. The exact organization varies by police system, so learn the broad language job rather than one supposedly universal structure.
And she's also got a holding cell,
A holding cell is much narrower: a secure cell used to keep someone temporarily in custody. So precinct is the broader police-place idea; holding cell is a specific secure space.
a ten-block perimeter.
A perimeter is a controlled boundary around an area. In an active search, officers may talk about securing a perimeter rather than a single room or building.
PERSON: perp, convict and fugitive are not synonyms
catch three perps so quickly?
The episode uses the plural perps. The singular perp is informal police/crime shorthand for perpetrator. It is TV-friendly, fast, and informal—but it is not a precise legal-status label, and learners should not use it as if it proves someone has legally been found guilty.
the last convict, George
A convict is different: the word points to conviction. It describes someone who has been convicted of a crime.
Your fugitive's name
A fugitive is defined by fleeing or avoiding capture. The same person can be described with different words because the words answer different questions.
Patrol officers have secured
Patrol officers is a job/role phrase. It describes officers whose work includes patrolling assigned areas and responding to incidents.
in front of two dozen eyewitnesses.
An eyewitness is someone who directly saw an event. That is a very different role from an officer, defendant, convict, or fugitive.
STATUS: “caught” has several different English labels
Do not memorize these as one rigid legal timeline. They answer different questions, and real procedure varies. For English comprehension, notice what each word tells you.
who are now at large.
At large means not captured or contained—still free while being sought.
They were arrested two months ago
Arrested means taken into legal custody. It does not itself mean convicted.
detectives were apprehended
Apprehended is a more formal “caught/taken into custody” word, common in reports and crime narration.
The pair are currently out on bail
Out on bail tells you they are not currently being held in custody while the case continues. Treat this as legal-media vocabulary; bail rules and procedures depend on jurisdiction.
but, if convicted, face
Convicted means formally found guilty. That is why arrested and convicted are not interchangeable.
ACTION: what police and investigators actually do
Search
this is a manhunt.
A manhunt is a large organized search for a wanted person.
He called the tip line.
A tip line is a channel for the public to give information or leads.
We have a lead. One of our witnesses saw
A lead is a clue or promising line of inquiry. A lead may help investigators find evidence; it is not automatically evidence itself.
Custody
It's our job to bring them in.
In police dialogue, bring someone in means take them into custody or bring them to the station for police handling.
Investigate
me interviewing witnesses.
Interviewing witnesses means questioning people who may know or have seen something relevant.
There's no evidence
Evidence is information or material used to support or challenge a claim or case. It is a broad category.
and security footage.
Security footage is recorded video from security or surveillance cameras. It can become evidence when relevant to an investigation.
We're gonna work this case,
To work a case means actively investigate or handle it. This is extremely common police-show English.
Court
don't need your testimony,
Testimony is evidence given by a witness in a formal legal setting. So evidence is the broader word; testimony is one particular kind of evidence.
We can't subpoena them.
Subpoena is formal legal vocabulary. In broad terms, it refers to legally requiring testimony, documents, or other evidence. Exact procedures are jurisdiction-specific, so treat this as language recognition rather than legal instruction.
Register strip: what sounds like TV-police shorthand?
| Register | Examples | What to notice |
|---|---|---|
| Informal police / crime-show shorthand | perp, rap sheet, bring them in | Fast, compact, common in dialogue; not automatically a precise legal classification. |
| Neutral / news-style | fugitive, at large, investigation, eyewitness | Often useful in news and general reporting as well as fiction. |
| Formal / legal | prosecution, affidavit, testimony, subpoena | More tied to court/legal contexts; meaning may be stable while procedures vary. |
rap sheet on him
Rap sheet is informal U.S. police/crime vocabulary for a criminal-history record or summary. It is useful for comprehension, but it is not the formal wording you would automatically choose in professional writing.
Okay. So, prosecution's case is strong.
Prosecution's case is clearly more formal/legal: it means the evidence and argument presented by prosecutors.
Do not mix these up
| Pair | Difference |
|---|---|
| precinct vs holding cell | Precinct = broader police district/station setting. Holding cell = specific secure cell. |
| perp vs convict vs fugitive | Perp = informal crime/police label. Convict = someone convicted. Fugitive = someone fleeing/avoiding capture. |
| arrest/apprehend vs convict | Arrest/apprehend concerns being caught/taken into custody. Convict concerns a guilty finding. |
| evidence vs testimony | Evidence = broad category. Testimony = witness evidence given formally. |
| lead vs evidence | A lead points investigators toward something worth checking; it is not automatically proof. |
Practice: classify the police English
Writer-original examples. Label each bold item PLACE, PERSON, STATUS, or ACTION.
A. “They took him to a holding cell.”
B. “The fugitive may have left the city.”
C. “The suspect is still at large.”
D. “Detectives are interviewing witnesses.”
E. “She works out of this precinct.”
Show the classification
A = PLACE. B = PERSON label. C = STATUS. D = ACTION. E = PLACE.
Practice: choose the better word
Writer-original examples.
A. The person has already been found guilty: perp / convict?
B. Police have not caught the escaped person yet: at large / convicted?
C. A new clue gives investigators something to pursue: lead / testimony?
D. A witness gives formal evidence in court: testimony / perimeter?
Show the answers
A = convict. B = at large. C = lead. D = testimony.
TV English is not a police-procedure manual
This page teaches vocabulary from a sitcom. Real police structures, bail rules, rights warnings, immunity agreements, subpoenas, charging language, and procedures can vary by jurisdiction and situation.
Use the article to understand what the words are doing in dialogue—not as legal advice or a guide to what police must do in a real case.
Build a police-English map instead of one giant word list
When a new crime-show term appears, ask one question: Is this a place, a person label, a status, or an action?
With FunFluen, you can pause on the line, reveal the subtitle, save the term with its category, and replay the next turn. That keeps perp, convict, fugitive, arrested, and convicted from collapsing into one blurry “crime word.”
Once those categories are clear, Brooklyn Nine-Nine gets much easier to follow—and you stop reaching for the dictionary every time the squad starts talking shop.
