Notes extracted from the CSS Criminology YouTube lecture series, Topic 10 — "Techniques of Investigation: Interview & Interrogation" (per FPSC syllabus). Compiled from academy notes (NOA, JWT, Near Peer).

Lecture Notes — Interview vs Interrogation

Investigative Interview

• A conversation conducted to elicit evidence and information from a person — witness, victim, complainant, or suspect — during the process of investigation
• Conducted with victims, witnesses, complainants, and suspects alike; the goal is simply to gather information/leads, not necessarily a confession

Interrogation

• A more formal, serious level of questioning of a suspect/person, aimed at obtaining incriminating information and a confession
• Only conducted where reasonable grounds for involvement already exist — not applied indiscriminately to everyone
• Described as "like an interview that is coercive" — involves an element of compulsion (the person does not have the option to simply decline to answer)
• Various techniques are used specifically to trigger a response/confession from the person
• Two types: custodial interrogation (subject is in custody and cannot leave) and non-custodial interrogation (subject is technically free to leave at any time)
• Aim: obtain documentary evidence/proof usable in court, with a confession as the prime example of such evidence

Lecture Notes — Importance of Interviews

• Interviews give an investigation its direction; material/evidence-gathering typically begins after the interview stage
• Interviews can lead to prosecution or early release of an innocent person — both outcomes matter
• Interviews save the prosecution case time, money, and resources by generating leads/evidence efficiently through direct conversation
• Interviews increase public confidence in the police service, particularly when victims and witnesses of crime are treated well and questioned properly — builds trust that police take their case seriously
• Without accounts from those who played a central role in the crime, or who witnessed important aspects of its commission, other sources of material (CCTV images, fingerprints, forensic material) — though extremely important — have comparatively little standalone value; the interview is what allows investigators to make sense of and interpret the fuller story

Lecture Notes — Interrogation Techniques (Named Approaches)

1. Direct Confrontation — the officer directly confronts the suspect with the accusation and evidence without giving any "chase"/room, e.g.: "We have your handprints on your wife, we have all the evidence — now just confess." No room is given to deny; the suspect is pushed straight to confession.
2. Dominance — investigating officers do not let the suspect speak/explain; they interrupt and dominate the conversation ("We have all the evidence, just do as you're told") to psychologically pressure the suspect into accepting guilt, since a dominated suspect is more likely to simply agree rather than resist.
3. Deflection and Minimization — officers offer a moral justification for the act (e.g. telling a suspect "yes you hit her, but it must have been her fault") — by minimizing/justifying the act (e.g. framing domestic violence as somehow provoked), the suspect becomes more willing to talk and may eventually confess.
4. Turning Objections — if the suspect raises an objection or excuse (e.g. "she kept nagging me"), the officer uses that very objection to justify the act back to the suspect, encouraging them to expand and eventually admit guilt.
5. Expressing Empathy — officers show empathy toward the suspect's situation/hardship, which can lower the suspect's guard and lead them to open up and eventually confess.
6. Posing the Alternative Question — officers present a stark choice/consequence ("you will lose your job, you won't be able to see your kids") to pressure the suspect emotionally into confessing rather than facing a worse alternative; can also involve suggesting a more sympathetic motive (e.g. "you did it because you didn't want to lose control of your household") that the suspect may accept and confirm.
7. Maximization — officers use tactics that make the suspect feel the matter is extremely serious (heightening perceived stakes/fear), increasing the likelihood of confession.
8. Bluffing Knowledge — officers falsely claim to already have complete information/evidence ("we saw you there, we already have an eyewitness") to trap the suspect into confessing, believing further denial is pointless.
9. Rapid Rapport-Building — officers build a personal rapport with the suspect (acting friendly, "I'm your friend") using simple understanding/empathy tactics, causing the suspect to let their guard down and confess.

Lecture Notes — Interview vs Interrogation: Key Distinctions

Past Paper Angles

• "Distinguish between interview and interrogation as investigative techniques."
• "Discuss the various interrogation techniques used by investigators to obtain a confession."
• "Explain why interviews are important to a criminal investigation."

Suggested Answer Outline

1. Define interview and interrogation
2. Importance of interviews — direction, efficiency, public confidence, contextualizing physical evidence
3. Interrogation techniques — direct confrontation, dominance, deflection/minimization, turning objections, empathy, alternative question, maximization, bluffing knowledge, rapid rapport-building
4. Comparative table — interview vs interrogation across purpose, planning, environment, relationship, approach
5. Conclusion — interviews and interrogation serve complementary but distinct roles; overreliance on coercive interrogation techniques raises confession-reliability and human-rights concerns (link to Chapter 11's legal/ethical guidelines)
