Direct PositiveConfrontation o State certainty in guilt ▪ Use fabricated or real evidence o Pause, observe, repeat confrontation o Passive reaction = deception o State purpose of interview is to figure out “why” o 2 Types of Suspects Emotional Non-Emotional Feels Distress/Remorse Nothing Particularly Interrogator Approach Sympathetic Factual Analysis Appeal to… Conscience Reasoning/Common Sense 2. ThemeDevelopment o Offer excuses/explanations for offence ▪ Allow for justification and rationalization o Possiblethemes for emotional suspects: ▪ Anyone in situation would have done same ▪ Minimize crime’s moral seriousness ▪ Suggest morally acceptable reasons ▪ Condemn others (e.g., victim) ▪ Praise and flattery o Possiblethemes for non-emotional suspects: ▪ Catch them in a lie ▪ Get suspect associated with crime scene ▪ Non-criminal intent behind act ▪ No point in denying involvement 3 ▪ Play one co-offender off the other 3. DoNotAllowDenials o Interrupt any attempted denials ▪ Repeated denials = less likely to confess o Innocent suspect ▪ Spontaneous, forceful, eye-contact o Guilty suspect ▪ Hesitant and defensive 4. Overcoming Objections o Allow objection and return to theme ▪ “I don’t own a gun” o Innocent suspect ▪ Continues with original denials o Guilty suspect ▪ Moves from denial to objections 5. Retain Suspect’s Attention o Deal with withdrawal by suspect o Use variety of behaviours to re-engage suspect ▪ Move closer ▪ Lean forward ▪ Mention first name ▪ Touch lightly ▪ Make eye contact 6. Handling Passiveness o Suspect is about to give in and confess ▪ Slumped shoulders ▪ Crying and/or blank stare o Focus on main theme & urge suspect to come clean ▪ Use sympathy and understanding 7. AlternativeQuestion o Present 2 explanations for crime ▪ One reprehensible, one face-saving ▪ Both produce a confession! o Most important component of Reid ▪ Problem for many suspect o Timing is critical 8. Relate OffenceDetails o Full details of crime 9. CreateWritten Confession o Written and signed confession more incriminating o Less important with videotaped interrogations Psychology BehindReid 4 - Confessing is difficult and unnatural o Internal and external concerns - Goals: o Reduce concerns through minimization and rationalizations Section 3: Problems withReidandConfession Admissibility ReidProblem 1: DetectingDeception - Behavioural Analysis Interview (BAI) initial step o Purpose is to decide if guilty o If yes, confession or bust - Reid technique based on deception detection o People can’t do it! o Training only increases confidence - Innocent person undergoes coercive interrogation ReidProblem 2: Investigator Bias - Assumption of guilt by interrogator o Ask more guilt-presumptive questions o More coercive o More persistent o More pressure - Suspect gets defensive – looks guilty by Reid ReidProblem 3: CoerciveTactics - Minimization: “Soft Sell” techniques o False sense of security o May imply leniency - Maximization: “Scare Tactics” o Intimidate suspect o False claims about evidence o Exaggerate seriousness of offence ReidProblem 4: Vulnerabilities - Current mental state - Mentally weak (IQ < 80) - Drugged/Intoxicated - Sleep Deprivations - Compliance & Suggestibility - State of Anxiety - Understanding of legal rights BeyondFalse Confessions - Inadmissible confessions that are TRUE! - Coerced confessions resulting in resentment - Coercion resulting in PTSD - Undermining public confidence - The “boomerang effect” 5 Admissibility of Confessions - For confessions to be admitted into court they must: o Be given voluntarily o Be given by a person who is competent - Terms rather ague and open to interpretation o Rely on legal rulings - Overtly coercive tactics not acceptable o Denying the suspect food, water, clothes, etc. o (R. v. Hoilett, 1999) - More subtle forms of coercion are acceptable o Exaggerating evidence, minim
