dr simon walsh, australian federal police - maximising the benefits of forensics to law enforcement
DESCRIPTION
Dr Simon Walsh, Chief Scientist Forensics, Australian Federal Police delivered the presentation at the 2014 Police Technology Forum. The Police Technology Forum 2014 seeks to address technology innovation, evolution and development within Australia’s law enforcement industry. In two days, a panel of experts gather to examine opportunities, initiatives and issues facing organisations both in front line policing as well as in wider law enforcement industry, including transport, border protection and surveillance.

Forensics
• Effective management of forensics must proceed out of a system-
wide awareness of its role and impact
This leads to a range of areas that forensic and law enforcement
professionals must comprehend and confront
• The relevant context is typified by distinct…
Technological,
Operational and
Socio-legal complexities
• The relevant context is investigative…
Seeking to provide answers to operational and legal enquiries

• Evidence items moving through multiple disciplines
• Repetition of core evidence examination steps
Segregated
• Disciplines operating separately in siloes
• Independent consideration of evidence
Independent
• Specialised skills dedicated to single discipline only
• Extensive quality assurance framework covering disciplines independently
Inflexible
• Stepwise analysis led to long turn-around times and backlogs
• Complicated customer interface frustrating for clients (investigators and courts)
Time Consuming
• Objective to produce sworn expert report and testimony
• Independent reports – multiple reports and experts in every case

Consultancy Model
“Operations support capability owners should be
consulted early during the planning stage to determine
how each can be best utilised. Through the consultative
process the investigator should nominate objectives
required and operations support will determine the most
suitable approaches for achieving those objectives”
AFP Investigations Doctrine
![Page 23: Dr Simon Walsh, Australian Federal Police - Maximising the benefits of Forensics to Law Enforcement](https://reader033.vdocuments.mx/reader033/viewer/2022052906/558ba7e7d8b42ae7358b4574/html5/thumbnails/23.jpg)

−Clear understanding of outcomes sought, priorities,
considerations and constraints
“Know where you want to end up”
−What does success look like?
−Very important for scientists!
−Fit-for-purpose vs. Fully evolved
“The importance of agility”
−Rapid prototyping
−Culture of innovation, action-oriented leadership, try-fail

Capability Management
•Well-understood notion of capability
Team Leaders as capability advisors
−Gateway to services
•Well-targeted investment in S&T, R&D, skills &
competencies
Drivers for R&D
−Increased value to operations
−Increased efficiency of operations
−Intelligence-oriented

Example: National Forensic Rapid Lab (NFRL)
•National Forensic Rapid Lab (NFRL) processes seizures
from parcel post for drug identification
•NFRL aims to:
Provide actionable intelligence to investigators
Produce operational actions to prevent, disrupt and detect
importation and distribution of illicit and novel drugs.

National Forensic Rapid Lab (NFRL)
• 350-500 items seized p/w
• Examinations consist of:
Record/Image
− Packaging/concealment method (digitise)
− Consignor/consignee details
− Country of origin & destination State
Scan & compare handwriting
− ‘FISH’ handwriting comparison software – 1 day TAT
Enhance and record latent Fingerprints
− Stand-alone ULP-ULP comparison - rapid TAT
Drug Identification & record drug net weight
DNA Collection (for Intell. confirmation only)
First 6 months
• Seized over 500kg drugs
• Same day examinations and
turnaround (~100 items)
• DHI >$125 million
• Novel Drugs average 1 p/w
![Page 30: Dr Simon Walsh, Australian Federal Police - Maximising the benefits of Forensics to Law Enforcement](https://reader033.vdocuments.mx/reader033/viewer/2022052906/558ba7e7d8b42ae7358b4574/html5/thumbnails/30.jpg)
Fingerprints and Intelligence
• The database contains latent prints that are:
Only collected from parcels post seizures
Unidentified and likely from overseas perpetrators (no NAFIS comparison)
• Between 30 March and 30 Oct 2013
1667 latent impressions added to database
• Simplified examination and search procedure
Able to process 100 latent fingerprints within a few hours
• Images undergo minimal processing by specialists
Vertically aligned, cropped and rotated (max. 1000 dpi)
Identifier number added
![Page 31: Dr Simon Walsh, Australian Federal Police - Maximising the benefits of Forensics to Law Enforcement](https://reader033.vdocuments.mx/reader033/viewer/2022052906/558ba7e7d8b42ae7358b4574/html5/thumbnails/31.jpg)
Fingerprints and Intelligence
• Searching on Fingerprint DB
No search parameters entered i.e. pattern type, code minutiae
Search algorithm produces a prioritised list of match candidates
• Confirmation of match
Single fingerprint expert examines the reported match
Intelligence link between seizures are reported to NFRL
− Not for court purposes
• 40% link rate for ULP-ULP comparisons
Second highest link rate behind package morphology
− 60% link rate overall
• Future state
Upgrade to automatic latent processing
− NFRL technical officers can upload
Apply to other scenarios (crime types)
