Unit 3 AC1.1 Flashcards
Evaluate the effectiveness of the roles of personnel involved in criminal investigations
Name a miscarriage of justice case you have researched

What does an SOCO do?
SOCO’s work alongside police officers to help solve crimes. They’re experts trained to take photographs of evidence and identify traces left at crime scenes. They attend a wide range of scenes including vehicle crimes, burglaries, murders and unexplained deaths.
What type of equipment does a SOCO use?
Cameras, paper bags, personal protective equipment, bodily fluid collection kits, evidence seals/tape, torches, measuring devices, tweezers and spray paint.
what are the Typical types of trace evidence searched for by crime scene investigators
hairs, Clothing fibres, Fingerprints, Skin cells, Body fluids/ tissues, Shoe prints
What are the limitations for a SOCO?
- the work requires specialist skills such as forensic photography as well as patience, care and attention to detail. Not collecting and recording evidence correctly or allowing it to become contaminated can lead to a guilty person going free or an innocent one being convicted.
- forensic samples that CSIs handle may but their health and safety at risk, for example: blood, bodily fluids, hazardous chemicals, explosives and incendiary devices, firearms and ammunition, knives and hypodermic syringes.
- this type of work can be stressful and very demanding emotionally especially when having to attend gruesome crime scenes or post mortem examinations.
Who was Meredith Kercher and what happened in the case of Amanda Knox and used in court to suggest the evidence collected was unreliable?
Meredith was a student in Italy when she was murdered, Amanda Knox was accused of killing Meredith, her roommate, in court evidence was declared contaminated and therefore unreliable. If pieces of evidence are collected and tested together without using new pairs of gloves and boot protector’s DNA from one object or crime scene can be passed on to other pieces of evidence.
what is the role of a forensic scientist and their role in a criminal investigation
Using scientific knowledge and expertise forensic scientists analyse and interpret evidence that has been recovered from the crime scene. Samples of blood or bodily fluids may be analysed in order for DNA to be extracted and compared with a ‘control sample’ taken from a suspect to see if there’s a match. Once this has been done, forensic scientists will produce a report of their findings and interpretations to present to the court. Most of the time forensic scientists will specialise in certain areas such as DNA analysis, fires in arson cases and toxicology in cases of poisoning or drug overdose.
Who was Adam Scott and what happened to cause the injustice?
A forensics error led to Adam being held for 5 months on a charge of rape in the UK. The DNA sample from the rape victim was contaminated during a routine DNA extraction procedure despite their being evidence he was at home in Plymouth at the time of the event.
explain a different miscarriage of justice case you have researched due to forensics evidence being incorrect?
Edward Spatt served 7 years in an Australian jail for the murder of Rosa Simpler, but he was later pardoned and given compensation in 1984 after the royal commissioner found evidence was unreliable and that some contamination of the crime scene has possibly occurred.
What are some of the limitations of a forensic scientist?
- because they are so highly qualified their services are expensive.
- contamination of evidence can occur when it is being examined by scientists.
- forensic experts may disagree and therefore because the court lacks specialist knowledge and may be unable to evaluate which side is correct.
- miscarriages of justice may occur if an expert deliberately or accidentally misleads the court.
what are the various roles within the police service that are specialists and consider how they contribute to the evaluation of the police in a criminal investigation. Is it case of too many cooks or is it highly effective?
CIDs deals with investigations into serious crimes. These count as robberies, burglaries, sexual offences, fraud, serious assaults and murders. CID officer sometimes assist uniformed officers in investigating the less serious crimes, such as theft. Police officers are a bigger class which includes CID officer, while a CID officer is a police officer posted in CID branch of the police
CID detectives primarily investigate felony-level crime and provide criminal investigative support to the Patrol Division.
Main responsibilities for CIDs include: Evaluate and prioritise the allocation of crimes, direct major incidents as required, supervise and participate in interviews, supervise and assist in the training of probationary officers and ensure that processes are in place to facilitate the transfer of intelligence gained during the course of investigation
how effective was the role of the police in the Stephen Lawrence investigation
The police’s incompetency in the murder case allowed the killers to go free because of prejudice in the ranks. This led to the Macpherson inquiry, which found the Metropolitan police guilty of institutional racism.
What was the Macpherson Report and what did it say in it’s findings about racism and the police?
The MacPherson report made 70 recommendations designed to show a zero tolerance for racism in society. The report found that the investigation into the killing of Stephen Lawrence had been “marred by a combination of professional incompetence, institutional racism and a failure of leadership”. 67 of the report’s recommendations led to specific changes in practice or the law within two years of publication and saw that the double jeopardy law was abolished. In addition, measures to transform the attitudes of the police and civil services towards race relations were implemented.
list some of the police failings in the investigation at the Hillsborough disaster
- A maximum number for the stadium capacity should have been given to the police in order to stop overcrowding and keep a record of those who entered. The turnstile should have been the only way of entering, the gates shouldn’t have been opened.
- A cut off time should have been decided prior to the event to stop overcrowding and more fans being able to enter.
- Exit gate C should have been monitored once opened.
- Kick off should have been delayed.
- Failure to prevent crowd congestion.
- The tunnel should have been closed
- The slow response from the emergency services.
What are some of the limitations of the police in a criminal investigation for instance Hillsborough?
- They can investigate and provide factual evidence, but cannot decide the innocence or guilt of the perpetrator
- In gathering their evidence, they must do so in a lawful way (there are certain things they’re not allowed to do e.g. they can’t extract evidence from a suspect via the use of violence)
- The police cant withhold evidence – In the Hillsborough disaster police withheld evidence that would’ve potentially incriminated them e.g. files detailing police cover-ups (later given to the Crown Prosecution Service (CPS)).
- Small rural police don’t have the same access to funding, resources and technology as some of the larger city forces do, which may lead to more time being spent solving a case or resulting in unsolved cases.
