Requires 1) actus reus (criminal act) and 2) mens rea (guilty mind)
Goals of punishment
Retribution
Deterrence
Retribution
Lex talionis – "an eye for an eye", Victim receives justice, Offender acts out of free will and understands what they are doing
Deterrence
Learn crime is associated with consequences, Specific deterrence: discourage specific individual from committing crime, General deterrence: discourage others from criminal activity based on potential consequences
If person cannot understand what they did was wrong, punishment would serve no purpose and does not meet goals of retribution or deterrence
Cannot be morally responsible for actions (did not understand actions were wrong), Cannot evaluate potential consequences
M'Naghten Case
1843: Daniel M'Naghten suffered from delusions and killed the Prime Minister's secretary (London), Jury found him not guilty by reason of insanity (NGRI)
M'Naghten Test
Presume defendants are sane/responsible until proven otherwise, At time of crime, defendant was operating with "defect of reasoning…disease of the mind" (had mental illness), At time of crime, defendant didn't understand what they were doing or didn't know it was wrong
Irresistible Impulse Test
They have a mental illness and it caused inability to control their actions/behave according to the law (i.e., volitional capacity), Can know that what they were doing was wrong, Problems: what is "too irresistible"? = failed to resist vs. could not resist, "Policeman at the elbow" test helps define what is "irresistible"
Durham Rule
Mental disease/defect = not responsible for criminal acts, Mental health professional can determine if behavior caused by mental illness (product test)
U.S. v. Brawner (1972)
Overturned the Durham Rule because the mental health expert would have too much influence on the outcome of the trial (issue with product test), Suggested using the American Law Institute (ALI) Model Penal Code Test
ALI Model Penal Code Test
Have a mental defect/disease and because of mental defect/disease, one lacks "substantial capacity" to: understand right from wrong (M'Naghten) OR control behavior (irresistible impulse/volitional capacity), then they are not responsible for the criminal act (NGRI)
Things that don't count as mental illness: Repeat criminal behavior, "antisocial conduct" (e.g., being intoxicated)
John Hinckley
1981: John Hinckley attempted to assassinate President Reagan, Tried to impress Jodie Foster, Shot four people (including president), 1982 trial - Prosecution given burden of proof to show defendant was sane beyond reasonable doubt, Mental health expert testimony - paranoid schizophrenia, Found NGRI - put in psychiatric hospital, 2016 - was released (with conditions), 2022 - release with no conditions
Insanity Defense Reform Act (1984)
Shifted burden of proof to defense (presume sane until proven otherwise), Proof = clear and convincing evidence, Stopped using volitional capacity (able to control behavior), Experts not allowed to give ultimate issue testimony (product test), Basically a version of the M'Naghten test - due to mental disease/defect, cannot appreciate crime or understand it was wrong
Insanity Defense Rules in the U.S.
All federal criminal cases use the Insanity Defense Reform Act, Most states use (modified) M'Naghten rule or Model Penal Code, Most states put burden of proof on defense, Some add irresistible impulse test, Some allow additional types of verdicts (e.g., guilty but mentally ill), States that DO NOT allow an insanity defense: Kansas, Idaho, Montana, & Utah
Insanity Defense Misconceptions
Hinckley's rich parents bought his verdict, "hired guns", expensive attorneys/experts, defense just trying to get client released, Mental illness = dangerousness, Insanity defense is used a lot, Those who use it are faking it, Used especially in violent criminal cases (i.e., dangerous criminals are going free)
Those found NGRI: Spend less time in prison/custody, Are released quickly
Some Facts about the Insanity Defense
74% believe mental illness can affect rational choice, but 66% against using insanity defense, 1% of felony cases have used insanity defense, Prosecutor and defense tend to agree on its use in these cases, Less than 33% of insanity pleas involve a murder, Insanity defense is not more effective than other defense strategies, i.e., using the insanity defense does not increase chances of NGRI verdict, Defendants using insanity defense are saying they committed crime, If it does not work - high probability jury thinks they are guilty
Some common characteristics among those using the insanity defense
Male, Non-violent crime, History of hospitalizations for mental illness, Psychosis, mood disorders (e.g., depression, bipolar), intellectual disability, Prior criminal record related to unsuccessful insanity defense, Malingering is RARE, Many have history of hospitalizations, diagnoses of major mental illness (e.g., psychosis)
Using insanity defense
Admitting they committed the crime
Most spend more time in custody vs. those who do not use insanity defense (similar crimes), Use insanity defense but NOT found NGRI - serve 22% longer sentence, If found NGRI - spend 2x amount of time in prison (9x for nonviolent offenders)
After an NGRI verdict: 84%-95% are hospitalized, 1%-4% unconditionally released
Guilty but Mentally Ill (GBMI)
Serve prison sentence consistent with crime, Required to receive mental health treatment or stay in psychiatric hospital, Does not guarantee they will actually receive treatment
Mens rea defense
Lack mental capacity to commit certain crimes, Prosecution has burden to prove mens rea, Could mean defendant can't be found guilty of 1st degree murder, Requires that one 1) knowingly/intentionally committed crime and 2) planned it, 2nd degree does not require this - heat of the moment
Diminished Capacity Defense
Different from insanity - did defendant have state of mind to act with purpose and intent, Think through consequences of action vs. know actions were wrong/control behavior, Example: What if M'Naghten knew actions were wrong, but due to mental illness could not think clearly enough when shooting the secretary?
Mental health examiners agree ~81% of the time when determining insanity, Judges follow recommendation of experts 91% of the time, When they do not - tend to find defendant sane
Problems with determining insanity: Retrospective judgment (mental state at time of crime), Insanity definition(s) vague, How do you quantify "substantial capacity", "severe mental disease"?, States vary in standard they use - hard to develop test to capture all components
Mental State at the Time of Offense Screening Evaluation (MSE)
Attempts to detect mental defect that could have affected behavior, Lacks standardized administration or scoring procedures
Created to capture the A.L.I. standards, Quantifies legal standards: e.g., volition, 25-items, Malingering, brain disorder present, major psychiatric disorder, loss of cognitive control, loss of behavioral control
Battered Women's Syndrome
Developed by psychologist Lenore Walker to explain behavior of women who experience intimate partner violence
Rape Trauma Syndrome
Originally created for use in therapy to understand symptoms/victim response to rape
PTSD
Trauma disorder classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM-V)
Intimate partner violence (IPV)
Can include physical violence, sexual violence, psychological/emotional abuse, and controlling behaviors
30% of women and 20% of men experience IPV in their lifetime
1 in 5 women will be physically assaulted by partner
1 in 14 men will be physically assaulted by partner
