C.S.U - Crime Scene Unit, Forensic Technician Personel. The unit is responsible for forensic investigations of homicides and sexual assaults, as well as other crimes as deemed necessary. Members of the Crime Scene Unit assist the precinct detectives in the processing of a crime scene as well as determining the proper routing of evidence. The Crime Scene Unit has many tools at its disposal to process a crime scene including the materials needed to develop fingerprints, cast footwear and tire impressions, follow the trajectory of bullets fired through windows and the chemicals necessary to observe blood under special lighting conditions that would otherwise be invisible to the naked eye. The unit is also trained to process a crime scene in a hazardous environment, for example following a nuclear, biological or chemical attack.
M.E - Medical Examiner, a physician, and a specialist in pathology or forensic science. Duties always include determining the cause, time, and manner of death. This uses the same investigatory skills of a police detective in most cases, because the answers are available from the circumstances, scene, and recent medical records. In many American jurisdictions any death not certified by the person's own physician must be referred to the M.E.
C.O.D - Cause of Death.
T.O.D - Time of Death.
E.S.U - Emergency Services Unit, is a police tactical unit which provides specialized equipment, expertise and support to the various units within the police departments. These police forces do not have a traditional S.W.A.T. unit. The Emergency Service Unit qualifies in the role of a S.W.A.T. unit and much more. From auto accidents to building collapses to hostage situations, "ESU" officers are called on when the situation requires advanced equipment and expertise.
T.A.R.U - Technical Assistance Response Unit a unit of the New York City Police Department who provides investigative technical equipment and tactical support to all bureaus within the department, in addition they also provide assistance to other City, State and Federal agencies.
LUDs - Local usage details, a list of a person's incoming and outgoing phone calls over a specified period of time. While LUDs are easy to obtain for police, they're not readily available at a cop's whim. Phone records are treated as private information, so investigators must prove to a judge that the search is warranted, in which case, the judge will grant a court order for the phone company to provide a suspect's LUDs.
Fishing expedition - when the police conduct a search they must have a definitive object in mind, they cannot just search in the hope of turning up some random evidence.
Hearsay - second hand witness testimony, a person repeating what they heard another say.
Miranda - the formal warning police are required to give suspects on arrest advising them of their right to remain silent, have legal council etc.
Lawyerd up - A suspect who invokes their right to not say anything and await their lawyer which the justice system will provide them.
Pro Se - A legal term used for someone who opts to represent himself/herself either in a criminal or civil court proceeding. While Pro Se is the proper term for it in New York, other jurisdictions call it Pro Per. A popular phrase associated with this is "He/she who represents himself/herself has a fool for a client. This is because self-representation is considered the most foolish act in the legal profession because private citizens don't have as much knowledge of the legal system at their disposal and don't have the same resources an attorney has to research and prepare for their case.
Probable Cause - The police having a reasonable degree of evidence to justify their actions.
'Fruit of the poisoned tree' - evidence that has been obtained improperly which may therefore be excluded from court. For instance a police officer searches a suspect and finds a weapon which is then linked to a murder. However the search is then ruled to be illegal due to insufficient grounds so the defence can argue that the evidence of the weapon should not be allowed to be introduced as part of the murder case.
Habeas Corpus - Latin for 'produce the body', that the accused should be able to confront their accuser in court, a legal principle dating back all the way to Magna Carta.
Man One/Two/Three - Manslaughter in the 1st/2nd/3rd Degree.
