Intelligence databases - answer-*The police use many databases to help them store
and access information to help in the fight against crime.
*E.g. the UK National DNA Database and Police National Computer or PNC, which
holds extensive information on people, vehicles, crimes and property. *It stores details
of over 12 million people's arrests, convictions and police cautions, with links to
biometric databases for fingerprints on the national DNA database.
*Vehicle registration data and information on 48 million people who hold a driving
licence, and those who are disqualified.
*The PNC also holds information on missing and wanted persons.
*The police national database contains intelligence about suspected criminal activity as
well as the data on the PNC.
*It holds over 3.5 billion searchable records and is itself made up of 220 linked
databases.
*Criminit, run by the Metropolitan Police Service of Greater London, stores information
on criminals, suspected criminals, and protesters. Also, there are databases that
contain information from witnesses, informants and agents.
*International databases - UK police can also access databases that share information
between police forces in different countries.
Forensics - answer-*Forensics today is very different from 100 years ago. In the past,
when police had to attend a crime scene, they would be alone until a doctor arrived to
confirm death and to carry out a very quick review of the body. In today's world of
forensic science;
}The police are accompanied by a range of forensic experts to help in the investigations.
}The police discuss actions and usefulness of various forms of evidence with the
experts.
}There is limited access to a crime scene, protective clothing is required to be worn, to
avoid contamination.
}The police recover evidence scientifically, which is then considered by a range of
experts in many different fields.
Crime watch - How they caught: Brian Keating's killers - answer-1. What type of crime
were the police investigating? A gang style killing.
2. Where was the body? What did this indicate to the police? Dumped in a church yard
in Leeds. He was propped up in the gravestones looking at the police.
3. How is Brian Keating described in the clip? He was no angel; he had been on the
wrong side of the law but was a loving family man.
, 4. Briefly describe the events of 15th October 2002. The gang broke into Brian's house
and took Brian with them into their car. A silent gunman held his wife and children at
gunpoint.
5. How were the police able to identify the suspects? Brian's wife knew the silent
gunman who had two brothers who had served prison sentences.
6. What evidence did the police use to trace the movements of the suspects? The
contact between the brothers.
7. What had happened to the car used in the crime? It was abandoned in a car park in
Leeds where they torched it.
8. What evidence was lea in the car? The sledgehammer which had Brian's blood on it.
9. How did the police trace the sledgehammer? They went to the store footage of where
the sledgehammer was bought and saw the brothers on CCTV buying sledgehammers.
10. How did this help to build evidence in the case? It showed Jaspal Khosa, and
Jetinder Khosa buying the sledgehammers that were used to kill Brian.
11. What evidence was on Brian Keating's body and face? Dog hairs but he did not
have a dog.
12. What evidence was found in the van? More dog hairs.
13. What was the problem with the DNA analysis of the evidence? They could develop
the DNA from the dog hairs but could not give any statistical evidence between the dog
and Brian.
14. Where did the samples get analysed? California
15. What was the chance of the DNA being from another dog? 1 in 484 million.
16. Why was the evidence from the dog so vital? The dog got the jury to con
DNA or deoxyribonucleic acid - answer-The chemical that carries genetic information
and is contained in chromosome found in the nucleus of most cells. Sometimes called
our genetic code as it determines all are characteristics.
Case study - first ever forensic use of DNA profiling - answer-*DNA profiling was
developed by the scientist Alec Jeffreys in 1985 and it was first used to investigate the
rape and murder of 2 girls in Leicestershire in 1983 and in 1986.
*Using the new technique, Jefferies established that semen left in both cases came
from the same man hold up police then took blood samples from all 4583 men in the
area and eventually found a match with Colin Pitchfork, who was convicted of both
murders.
*The test also exonerated Robert Buckland, a 17 year old with learning difficulties who
had admitted to the 1983 killing hold up Buckland became the first person ever to be
cleared of a crime using DNA analysis.
*However, Pitchfork was in fact only caught when a Co-worker revealed to work mates
that he had taken the blood test masquerading as Pitchfork, because Pitchfork told him
he had already given a sample while pretending to be a friend he wanted to avoid being
harassed by police because of a previous conviction.
*A woman over heard the conversation and reported it to the police.
*The DNA analysis confirmed pitchfork's guilt but it was the witness evidence that
enable police to catch him.
*The forensic evidence was not the only factor.
