AR	Armed Robbery From smackheads with sawn-offs in the servo to large shipments of gold bullion hidden in garden gnomes, the detectives at Armed Robbery deal with a large scope of dangerous crime.
CCU	Computer Crimes Unit Every man and his nana are online these days; it's the information age. The Computer Crimes Unit is now an integral part of solving crimes and a key resource for our Homicide detectives.
CI	Crime Investigation This is what our detectives do.
CIU	Crime Investigation Unit This is a fancy name for a police station with a detectives division.
DPP	Director of Public Prosecutions/Office of Public Prosecutions These are the people who decide whether a case is strong enough to be prosecuted in a Court of Law. Gut instinct isn't good enough for the DPP. Our detectives have to present them with a strong case. They need to collect all the evidence, confessions and make sure it's water tight. The DPP may bust the Detectives balls from time to time, but they want the same thing as we do - killers behind bars.
ESD	Ethical Standards Department This Police Department investigates complaints made about police members and also any police shootings, police vehicle accidents and escapes from custody. The people our cops don’t want to get a memo from. Unwanted scrutiny and time spent in interview rooms when they could be catching crims. But as long as our guys keep squeaky clean, it's no drama. Just part of procedure. Duncan's had more than his share of attention from ESD.
MCIU	The Major Collision Investigation Unit are called in when there is a multiple vehicle collision or multiple fatalities. Generally these guys deal with accidents, but occasionally there's something fishy for Homicide to investigate.
SOG or SOGGIES	Special Operations Group The dudes in the black jumpsuits who carry big guns and run in delicious formation. May be heard uttering phrases like "perimeter is secure" or "standing by to assist with evac of shooter".
OPI	Office of Police Integrity An independent authority which investigates allegations of corruption and misconduct made against Police Members Police corruption - the newspapers love it and it certainly exists. There's always going to be a few bad seeds who get tempted over to the dark side.
GSR	Gun Shot Residue Scientists swab the hands of suspects then analyse for traces of gun shot residue. So far on screen our detectives haven't nailed a supect using Gun Shot Residue, but they often end up with some on their hands after an altercation with a dodgy, gun-toting and dangerous suspect.
KALOF	Keep A Look Out For An acronym for a communication that goes round to alert police to keep a look out for a person of interest.
VIN	Vehicle Identification Number You can change the number plates but you can't change the VIN. The VIN is a series of numbers and letters that are unique to your car. It's like your car's DNA - telling you all about your car's history. Our detectives will always check VINS when trying to track a car's history.

HOMICIDE LINGO

BALLISTICS	A Senior Constable or Sergeant who has had specific training in dealing with shootings AKA a handy device to reveal information. Fortunately, ballistics and forensics tests take a long time to carry out so the detectives have time to investigate likely suspects, and get an idea of their backstory before any incriminating evidence is revealed.
BLOOD SPATTER EXPERTS	Biologists who are trained in recognising and analysing blood spatter patterns If you get over the grossness, this would be a way cool job. Simon's got a pretty good handle on all this stuff.
CRIME SCENE	Police members with specific training. They collect, tag and log all exhibits at a crime scene These guys wear nifty jumpsuits and help provide our detectives with all the available, gruesome evidence.
CRIME SCENE EXAMINER	A Police Member, usually a Senior Constable or Sergeant, with specific training who leads the other Crime Scene police at a murder scene This person gets to boss around the people in nifty jumpsuits.
CRIME SCENE PHOTOGRAPHER	A Uniformed Police Member who has had Crime Scene Photography training Takes some pretty gory photos - not the sort of happy snaps you'd take home to show Nan.
FILE FLAGS	Incident highlighters (The colour of the flag indicates the level of incident, black being the highest level) These appear on Police Personnel Files and on criminal's files. On Personnel Files they indicate when a detective has had a clash with a superior, or crashed the squad car, or shot someone, that sort of thing. Duncan has heaps of flags on his file. On a Crim's file it might indicate something our cops should be aware of, eg. if someone escaped from custody or attacked a police member.
INTERVIEW ROOM	The room where suspects or Persons of Interest are questioned by our Detectives This is the room where Duncan, Jen, Matt and Simon break down the suspects, and get a confession involving the reveal of backstory and motivations.
MUG SHOT	An official police photo of an arrested offender Taken through a special photographic filter so that you look as unattractive and suspicious as possible.
PERSON OF INTEREST	Someone who helps our Detectives with their investigation into a homicide. This person may end up being a suspect POI - sounds a little like a onamatopea for a bouncing ball, but it's really just a nice way to say "watch this space".
POLICE MEMBERS	Police - including Uniforms, Detectives and Crime Scene "Members" is guaranteed to get a giggle from the more junior members of the script team.
POL SEARCH	Police File Search (if persons of interest has a record, all information will come up on the pol search) A Polsearch is likely to list previous crimes that the suspect being investigated has commited - Driving Under the Influence, Intentionally Cause Serious Injury, Endangering Saftey of Aircraft, and so on. Plus, any outstanding parking fines. That's got Evildoer written all over it.
RANKINGS	The structure of positions within the State Police - the higher the rank the greater the authority Can also affect how you dress. Sergeant Hatzic wears a uniform, whereas being a DSC in Homicide means it's MUFTI day every day for Jen, Duncan, Simon and Matt, and that the boys can wear a large array of pale pastel shirts.
STATEMENT ROOM	The room where family members of victims and children as well as witnesses who are not suspects are questioned by our Detectives A generally friendlier environment than the interview room; there's toys to play with.
