Fighting crime with science

my lecture notes part1.

conducting any experiment
process forensic intelligence
insider => who must have know professor
crime event is a history
disturbed by evidence
finger prints: invisible to the naked eye, visible in black light, reacts with acid

*most criminals are a little bit smart

DNA detection: DNA's are unique . Only identical twins have the same DNA

*crime scene which DNA was taken from
-closer look at the desk (dust contained DNA)
-hair of murderer
-dust in the air contained 100 DNA cells

forensic laboratory : most reliable way yet

DNA: twisted ladder, maintain life, A,G,T proteins repeat
in UK, 1/60000 , the rate of the chance of having the same dna
-drug,roof,hair, follicular.. dissolve the protein

DNA evidence ; small piece is enough because technology improved too much

*unsolved crimes are now can be cleared up with information transformation

measure the lens of DNA
nationale DNA database: 1/1000000 (in the future =>decode the DNA)

*genetic photo to trace the killer

ESLA (Electrostatic Lifting Apparatus) : distinguished to the naked eye
-electrons are transferred one material to the other (6000 watt)

*type of shoe identified (unique footprint, markings of the shoe)

gunshot residue : detecting the presence of residue
recognition: spotted by witness

VIPER: video identification procedure
human level in recognition is very hard , that's why facial recognition systems are used . they treat the face and analyze-reduce, compare with other faces, key measurements are eyes , nose , mouth etc.

blind fold: forehead face shape, facial recognition

autopsy record
computers help piece together all the evidence
analyze intelligence system developed by the police aims to reduce the work

*new system:creating people for committing crime (names ,addresses, other people )

CCTV: over 400, scrutinized town public security
automatic plate recognition
