Law Enforcement Investigation Skills Training Course

Participants can assess an initial report and determine immediate investigative priorities.

Participants can assess evidence against competing case theories and evidential tests.

• Relevance, reliability, admissibility and weight assessed for each evidential item
• Evidence matrices map facts in issue against available proof
• Direct, circumstantial, documentary and testimonial evidence distinguished accurately
• Corroboration needs identified without assuming identical accounts equal truth
• Alternative hypotheses tested against contradictions, omissions and independent evidence
• Evidential gaps converted into focused, proportionate investigative actions

Participants can plan lawful, respectful and evidentially useful witness engagement.

• Witness needs assessment considers safety, vulnerability, trauma and communication
• Contact plans set purpose, timing, privacy and safeguarding arrangements
• Memory contamination risks reduced through neutral pre-interview communication
• Witness accounts separated from investigator interpretation and opinion
• Victim updates record information provided, concerns raised and agreed actions
• Protection measures considered where intimidation, retaliation or disclosure risks arise

Participants can plan and conduct witness interviews using the PEACE framework.

• PEACE framework structures planning, engagement, account, closure and evaluation
• Rapport-building establishes roles, purpose, ground rules and communication needs
• Open invitations obtain free narrative before focused clarification questions
• TED prompts encourage Tell, Explain and Describe responses
• Cognitive interview prompts support recall without introducing suggested information
• Interview evaluation identifies new enquiries, inconsistencies and welfare actions

Participants can prepare a legally compliant suspect interview plan based on evidence.

• Suspect interview objectives derived from facts in issue and evidence
• Disclosure strategy balances fairness, investigative integrity and local legal requirements
• Question sequences progress from account, clarification, challenge and explanation
• Interview topics distinguish known facts, reasonable inferences and unresolved issues
• Potential defences anticipated through evidence-led, non-assumptive questioning plans
• Legal safeguards, breaks, welfare needs and recording arrangements documented

Participants can conduct ethical, structured suspect interviews and evaluate the account obtained.

• PEACE interview stages applied to suspect questioning and account testing
• Active listening identifies admissions, denials, explanations and new lines
• Evidence presented strategically without deception, coercion or oppressive conduct
• Challenge questions test inconsistencies against reliable, disclosed evidence
• Interview records distinguish exact responses from investigator summaries
• Post-interview evaluation determines verification actions and further interviews

Participants can identify, obtain and analyse documentary evidence for investigative use.

• Document requests specify custodians, date ranges, formats and preservation requirements
• Original records distinguished from copies, extracts, summaries and translations
• Provenance checks establish document creator, source, date and integrity
• Transaction timelines connect payments, approvals, communications and relevant events
• Benford's Law limitations understood when screening potentially anomalous numerical records
• Document schedules identify relevance, evidential purpose and outstanding verification

Participants can preserve and request digital material without compromising evidential integrity.

• Digital evidence triage identifies devices, accounts, platforms and volatile data
• First responder actions prevent alteration, remote access and data loss
• Device seizure records capture condition, power state and connected peripherals
• Hash values verify digital-file integrity during transfer and review
• Preservation requests identify accounts, date ranges and relevant data categories
• Specialist examination requests state investigative questions, not assumed conclusions

Participants can convert intelligence into assessed, lawful and actionable investigative leads.

• Intelligence differentiated from evidence, rumour, inference and unverified allegation
• Source evaluation records access, reliability, motive and corroboration opportunities
• 3x5x2 intelligence grading applied where organisational procedures require it
• Link analysis maps people, entities, communications, assets and events
• Timeline analysis reveals sequences, gaps, opportunities and conflicting accounts
• Analytic judgments state confidence levels, assumptions and information gaps

Participants can identify, record and manage material requiring disclosure assessment.

• Unused material identified from notes, recordings, exhibits and digital returns
• Disclosure schedules describe material accurately without argumentative characterisation
• Potentially exculpatory information flagged early for supervisory assessment
• Sensitive material handled through access controls and documented decision routes
• Data minimisation limits collection, retention and circulation of personal information
• Disclosure review points scheduled after significant evidence or theory changes

Participants can create clear, chronological and review-ready investigation records.

• Contemporaneous notes separate observation, action, information and professional judgment
• Decision logs record authority, rationale, alternatives and review dates
• Chronologies integrate incident facts, evidence events and investigative activity
• Case-management entries use precise dates, times, sources and references
