Criminal Justice: Key Concepts and Case Process (Notes) 9/9

Criminal Justice: Key Concepts and Case Process (Notes)

• Three core components of the criminal justice system

  • Police, courts, and corrections

  • Each component plays a distinct role in processing cases from investigation to rehabilitation

  • Due process ensures the offender’s rights are protected throughout the procedure

  • Fairness and objectivity are emphasized, but the system recognizes both objective standards and the realities of human judgment

• Justice and due process

  • Justice is described as aiming for objectivity, with personal feelings set aside by agents of the system (though this can be difficult in practice)

  • Due process covers the offender’s rights during search and seizure, trial, and time served

  • The system includes three core components and due process across the entire procedure

• Models of criminal justice: consensus vs. conflict

  • Two overarching models: consensus and conflict

  • The United States tends toward the conflict model in practice, though consensus is desired for cooperation

  • Resource constraints, funding limits, and competition for resources contribute to conflict between components

• Ethics and professional challenges in criminal justice

  • Ethical dilemmas are common and can be difficult to resolve

  • Examples of ethical tension: representing clients who admit guilt, ensuring rights are protected while pursuing truth, and balancing public safety with individual rights

  • High-profile examples discussed: George Floyd case (Chauvin), Chris Watts, O.J. Simpson, Jodi Arias, Son of Sam (David Berkowitz)

  • Public safety exceptions can allow questioning without Miranda rights in extreme scenarios (e.g., Boston Marathon bombing era) under certain conditions (terrorist threats)

  • Patriot Act and related public safety considerations can temporarily affect the application of Miranda rights in terrorist threats

  • Ethical education is emphasized as essential for all core components (police, courts, corrections, defense and prosecutorial roles)

• Five stages of a case (illustrated via cases like Brian Kohberger and others)
  1) Investigation and arrest

  • Investigation precedes arrest; probable cause is required and is based on facts and evidence (e.g., footprints, DNA, video, etc.)

  • Example narrative: multi-layer investigation with security footage review, DNA testing, and pattern analysis leading to an arrest

  • Common types of evidence discussed: fingerprints, hair/DNA, blood, video cameras, eyewitnesses, phone footage, security cameras, doorbell cameras

  • Direct evidence (what you saw) vs. circumstantial evidence (inferences from related facts) vs. trace/physical evidence (DNA, fibers, etc.)

  • Transmission from evidence to arrest relies on corroboration across multiple sources
    2) Booking and Miranda rights (arrest phase)

  • After arrest, the person is detained in custody and undergoes booking: fingerprints, mugshot, possible clothing collection, DNA or hand swabs

  • Interrogation typically follows a Miranda warning; a suspect can invoke the right to remain silent and to counsel

  • Miranda rights remind: right to remain silent, anything said can be used against you, right to an attorney, if you cannot afford one, one will be provided

  • Miranda must be given prior to interrogation in most situations; spontaneous utterances (things said in the car or en route) can still be used in some contexts

  • The field vs. station approach: Miranda rights are often shown in media at the moment of arrest, but they must be formally acknowledged before interrogation begins in custody

  • Public safety exceptions exist (e.g., terrorist threats) where interrogation may proceed without standard Miranda warnings for a limited time to prevent imminent harm
    3) Pretrial: first appearance, arraignment, bail, and plea discussions

  • First appearance/arraignment must occur within $48\,\text{hours}$ of arrest (often referred to as the initial appearance or arraignment)

  • Bail, bond, or conditions may be set; electronic monitoring or a probation officer may be assigned

  • Court-appointed attorneys or public defenders are provided if the defendant cannot afford private counsel

  • The court determines whether the defendant is held pending trial or released under conditions

  • Plea bargaining often occurs before trial; the defense and prosecution may negotiate lesser charges or a reduced sentence
    4) Preliminary hearings and grand juries; indictments

  • A preliminary hearing or grand jury determines if there is enough evidence to move forward

  • Indictments result from a grand jury’s decision that there is probable cause to proceed; a preliminary hearing serves a similar function with a judge

  • Distinction: grand juries are juries (peers) deciding whether to indict; preliminary hearings involve a judge deciding whether to proceed to trial

  • Notable terms: indictment indicates enough evidence to move to trial; if not indicted, the case may be dropped or reopened with further evidence
    5) Plea and trial; sentencing; corrections

  • Pleas: Guilty, Not Guilty, No Contest (nolo contendere)

  • Insanity defenses are a form of not guilty by reason of insanity (not a standalone plea); competency to stand trial is evaluated prior to trial

  • Plea bargaining is common; many cases settle with a guilty plea to a lesser offense or adjusted charges to avoid trial

  • If not guilty enters trial, the Sixth Amendment guarantees right to a jury trial (for most offenses); bench trials are possible where a judge acts as fact-finder

  • Verdicts: acquittal (not guilty) or conviction; if guilty, sentencing follows

  • Capital cases: the death penalty is determined by a jury in many jurisdictions; sentencing can be influenced by aggravating and mitigating factors, totality of circumstances, and possible parole considerations

  • If found guilty, the judge imposes a sentence; deaths penalty decisions involve jury verdicts on whether to impose death; unanimity is typically required for verdicts in serious cases

  • After sentencing, corrections and reentry processes begin; most offenders eventually reenter society under various supervision levels (probation, parole, community-based programs), with a growing emphasis on rehabilitation to reduce recidivism

• Evidence types and how evidence shapes arrests

  • Direct evidence: eyewitness accounts of the crime (e.g., “I saw X commit the act”)

  • Circumstantial evidence: suggests a crime occurred and a suspect’s involvement without direct observation (e.g., relationship histories, pattern of behavior)

  • Physical/trace evidence: DNA, fingerprints, hair, blood, fibers, gunshot residue (GSR)

  • Video and surveillance: doorbell cams, store/security footage, mobile phone video; mass surveillance can provide critical leads

  • Eyewitness testimony: may be compelling but can be unreliable; corroboration with other evidence is often essential

  • Forensic science: DNA analysis, genealogy (genetic evidence linking suspects to scenes or relatives’ DNA in databases)

• Notable case-based discussions and ethical considerations

  • Brian Kohberger case (Idaho serial killings): investigation, collection of evidence, DNA from suspects’ relatives, and eventual arrest; emphasis on statutes, warrants, and the procedural steps from arrest to charging

  • Chris Watts case: spouse involved; polygraph results; confession process; ethical concerns around defending a client who admits guilt

  • O.J. Simpson case: not guilty verdict despite public controversy; double jeopardy implications; later civil case strategies (guilt in civil court vs. criminal acquittal); public perception and legal outcomes

  • Jodi Arias case: death penalty considerations; multiple aggravating circumstances; voir dire and jury dynamics; death penalty unanimity rules (Arizona’s two-jury approach for capital cases historically) and debates about sentencing

  • Son of Sam (David Berkowitz): mental health/psychological influences on violent crime; the role of delusions/hallucinations in some criminal defenses

  • Public safety vs. individual rights: Boston bomber and Patriot Act-inspired measures; public safety can, in rare instances, affect the timing and manner of Miranda warnings

  • Voir dire and bias: the process to ensure an unbiased jury; the importance of juror impartiality and exclusion for non-compatibility with a fair trial

• Miranda rights, interrogation, and the Fifth Amendment

  • Miranda rights come from the 1966 Miranda v. Arizona decision; right to remain silent and that anything said can be used in court; right to an attorney

  • Interrogation should generally occur after Miranda warnings; if a suspect requests an attorney, questioning must cease

  • Spontaneous utterances in the car or during transport can sometimes be used, but formal interrogation without warnings is generally limited

  • Public safety exception allows authorities to question without warnings in urgent scenarios related to preventing harm

  • If Miranda rights are not properly administered, a defendant’s statements may be suppressed; this can affect the case and potentially lead to dismissal or suppression of evidence

  • The distinction between field and station warnings; the theory that law enforcement often issues rights when a person is about to be interrogated, not necessarily at the moment of arrest

• Pretrial process specifics

  • First appearance: within $2\times24 = 48\,\text{hours}$ of arrest; defendant informed of charges and rights

  • Bail considerations: electronic monitoring, probation officers, or other restraints may be ordered to ensure appearance in court

  • Appointment of counsel: if unable to afford, public defender or court-appointed counsel is provided

  • Preliminary steps: probable cause and evidence review before moving toward indictment or trial

  • Plea options discussed during pretrial stages: guilty, not guilty, or no contest; plea bargaining can occur here to avoid trial

  • Competency to stand trial: a competency evaluation may be conducted; insanity defenses often involve psychological evaluations and can require competency assessments

• Trial process: jury vs bench; the Sixth Amendment and beyond

  • The Sixth Amendment guarantees the right to a trial by jury; in some cases, a bench trial (judge-only) is possible

  • Grand juries vs trial juries: grand juries determine whether to indict; trial juries determine guilt or innocence; both serve different purposes and involve different jurors

  • Plea bargaining is common; most cases (roughly $80\%\text{–}90\%$ in various sources) are resolved by plea rather than going to trial

  • If found not guilty (acquitted), the defendant goes home; double jeopardy prohibits retrial for the same offense after an acquittal

  • If found guilty, sentencing follows; the judge imposes the sentence in most cases, except capital cases where juries determine death eligibility

  • Sentencing and aggravating/mitigating factors: totality of circumstances, the nature of the offense, prior convictions, and offender characteristics influence whether sentences run consecutively or concurrently

  • Consecutive vs. concurrent sentences

  • Consecutive: sentences run one after another; total is the sum of each sentence

    • Example: third-degree arson (5 years) + weapons charge (1 year) + battery (2 years) = $5 + 1 + 2 = 8\,\text{years}$

  • Concurrent: sentences run at the same time; the total is the longest individual sentence

    • Example: if all charges are concurrent, the total would be the highest single sentence, e.g., $5\,\text{years}$

  • Capital punishment specifics: in death penalty cases, the jury typically decides whether to impose the death penalty; unanimity is often required for death verdicts; some jurisdictions historically allowed multiple juries; modern practice emphasizes a single unanimous jury verdict

  • Notable considerations: public sentiment, the possibility of appeal, and potential for mistrials due to juror misconduct or prosecutorial issues

  • Common defense strategies at sentencing: challenges to aggravating factors, arguments for mitigation, and consideration of mental health conditions (e.g., guilty but mentally ill) or insanity defenses

• Corrections and rehabilitation

  • Corrections involves executing the sentence and preparing the offender for reentry into society

  • There is a shift toward community-based consequences (probation, parole, house arrest, community service) alongside incarceration

  • Rehabilitation programs (education, vocational training, treatment) are increasingly emphasized to reduce recidivism; roughly 80% of felons are expected to reenter society, underscoring the focus on rehabilitation

  • Three strikes/habitual offender laws: historically increased penalties for repeat violent offenses; policies have evolved but long-term incarceration remains a feature of some jurisdictions

• Key takeaways and foundational implications

  • The justice system aims to balance objectivity with ethical and practical realities; due process is central to protecting individual rights

  • The system includes distributed checks and balances (police investigations, court proceedings, and corrections/sentencing), each with its own set of rules, procedures, and ethics

  • The distinction between direct, circumstantial, and physical evidence is foundational to trials and the evaluation of probable cause and sufficiency of evidence

  • Plea bargaining is a core practical feature of the system, shaping outcomes in the vast majority of cases; trials are more rare but essential for establishing legal precedents and protecting constitutional rights

  • Understanding the interplay between constitutional rights (Sixth and Fifth Amendments), procedural safeguards (Miranda warnings, voir dire), and prosecutorial discretion (indictments, plea offers, sentencing) is essential for exam readiness

• Quick reference to recurring terms and concepts

  • Due process, objective justice, and ethical dilemmas

  • Consensus vs. conflict models; resource constraints and intercomponent tensions

  • Investigation concepts: probable cause, evidence, direct vs. circumstantial vs. physical (trace) evidence

  • Key procedural milestones: arrest, booking, Miranda rights, first appearance/arraignment, bail, prelim/grand jury, indictment, plea, trial, sentencing, corrections

  • Notable case anchors: Kohberger, Watts, O.J. Simpson, Jodi Arias, Son of Sam, Chauvin, Boston bombing context, Patriot Act/public safety exception

  • Legal rights: Fifth Amendment (right against self-incrimination), Sixth Amendment (right to counsel and trial by jury), double jeopardy protections, and the role of competent mental health evaluations in the process

• Practical exam-oriented notes

  • Expect questions about the three pillars and their roles, the difference between grand jury vs preliminary hearing, and the meanings of indictment vs arraignment

  • Be ready to explain consecutive vs concurrent sentences with numerical examples

  • Distinguish between direct, circumstantial, and physical evidence and provide examples

  • Explain when Miranda rights must be given and what constitutes spontaneous utterances

  • Describe the difference between plea options and when plea bargaining typically occurs; understand insanity vs competency concepts and how they impact case progression

  • Know the role of the jury in death penalty decisions and the requirements for unanimity

  • Recognize the shift in corrections toward rehabilitation and community-based sanctions, and how this affects recidivism rates

• Illustrative numerical anchors (for quick recall)

  • Arraignment/first appearance deadline: $48\,\text{hours}$ after arrest

  • Typical timeframes referenced in class discussion: $2\ \text{days}$, $12\ \text{hours}$, $14\ \text{hours}$, $82\%$ in one referenced context, $80\%\text{–}90\%$ for cases resolved by plea rather than trial

  • Most cases resolved by plea: approximately $80\%\text{–}90\%$; trials occur in a minority of cases

• Notes on media examples and caveats

  • Media portrayals (OJ Simpson, Chris Watts, Kohberger, Jodi Arias, Son of Sam) illustrate various ethical, procedural, and evidentiary issues but do not always reflect exact legal outcomes or procedural timelines

  • Real-world cases can involve appeals, mistrials, and post-conviction developments that alter initial perceptions

• Summary takeaway

  • The criminal justice system comprises interconnected stages, each governed by rules designed to protect rights while pursuing truth

  • Understanding the procedural flow (investigation → arrest → booking/ Miranda → pretrial → trial/plea → sentencing → corrections) plus the nature of evidence and the role of ethics is essential for exam success
