NJ Police Lieutenant cheat sheet

Span of control: a sergeant's effective direct-report range is commonly 6-10 officers; wider spans require more delegated authority and documented performance checks.

Situational leadership model: directing (high task/low relationship) for new or probationary officers, coaching (high/high) for developing officers, supporting (low task/high relationship) for competent but variable performers, delegating (low/low) for proven veterans.

Discipline progression absent a contract clause or egregious misconduct: documented counseling, written reprimand, suspension, demotion, termination; each step requires notice and a written record.

Progressive discipline is weakened where the employer cannot show the prior step was issued in writing and acknowledged by the employee.

Leadership vs. management distinction: leadership sets direction and climate; management allocates resources, schedules, and enforces policy. A lieutenant typically performs both.

Accountability chain: the lieutenant answers for squad outcomes even when a subordinate committed the act; failure-to-supervise is a separate chargeable offense in most NJ agencies.

Shift briefing (roll call) content: BOLOs, warrant hits, crime pattern updates, training notices, equipment checks, and personnel assignments, all documented in the shift log.

Critical decision model for supervisors: gather facts, identify legal authority, weigh use-of-force and liability exposure, act, then document contemporaneously.

Case screening factors: solvability (witness availability, physical evidence, identifiable suspect), seriousness, and prosecutorial interest drive assignment priority.

Chain of custody: every transfer of evidence records date, time, from/to person, purpose, and seal condition; a break in the chain invites a challenge to authenticity, not automatic exclusion.

Linkage analysis compares modus operandi, victimology, time/place clustering, and physical evidence to connect offenses to one offender.

Investigative checklist for violent crime: scene security, medical response, witness canvass, evidence collection, neighborhood canvass, video retrieval, BOLO, and follow-up assignments.

Case file components: initial report, supplemental reports, evidence inventory, witness statements, photo arrays, lab requests, and chronological case activity log.

Photo array best practice: sequential presentation, blind or double-blind administrator, fillers matching suspect description, and documented witness instructions that the suspect may not be present.

Cold case review triggers: new DNA technology, new witnesses, convicted offender database hits, and change in case status or investigator assignment.

Solvability is not clearance; a case is cleared by arrest, exceptional means, or unfounded determination, each requiring documented justification.

NJ Criminal Code (Title 2C) grades offenses: first degree (10-20 years, up to $200,000), second (5-10 years, up to $150,000), third (3-5 years, up to $15,000), fourth (up to 18 months, up to $10,000), disorderly persons (up to 6 months, up to $1,000).

Search warrant requirement: warrants issued by a judge upon probable cause; telephonic and electronic warrants are permitted under N.J. Court Rules for exigent circumstances.

Arrest without warrant requires probable cause that an offense was committed; for disorderly persons offenses, arrest authority is limited to offenses committed in the officer's presence or as authorized by statute.

Miranda custody plus interrogation triggers warnings; routine booking questions and volunteered statements do not.

NJ bail reform: pretrial release decisions are made by the court under the Criminal Justice Reform Act; monetary bail is largely replaced by risk assessment and conditions.

Terry stop requires reasonable suspicion of criminal activity, articulable facts, and a stop of limited duration; a frisk requires reasonable suspicion the person is armed and dangerous.

Use-of-force standard: force must be objectively reasonable; deadly force is limited to defense of life or preventing escape of a suspect who poses a threat of serious bodily harm.

Statute of limitations: most crimes have no limit for first-degree offenses; lesser offenses generally carry a 5-year limit, with specified exceptions.

Directed patrol uses crime analysis to assign officers to specific times and places; random patrol alone has limited deterrent effect.

Hot spots policing targets micro-places; evidence supports short, repeated patrol visits rather than saturation.

Community policing pillars: organizational transformation, community partnerships, and problem solving (SARA: scanning, analysis, response, assessment).

Broken windows theory links disorder and minor offenses to fear and more serious crime; enforcement must be paired with community engagement to avoid legitimacy loss.

Patrol deployment formulas consider calls for service, response time targets, and officer availability; a common target is that 30-40% of time is uncommitted for proactive work.

CompStat-style accountability meetings review crime trends, hot spots, and follow-up actions; data must be validated before presentation.

Traffic stops: the stop must be based on a violation or reasonable suspicion; the stop's duration must be limited and questions related to the stop's purpose.

Bias-free policing requires documented reasonable suspicion articulable apart from race, ethnicity, or national origin; data collection supports supervision review.

Report content: who, what, when, where, why, how; plus actions taken, evidence collected, witnesses, and disposition.

Use first person, past tense, active voice, and chronological order; avoid opinions, conclusions, and jargon without definition.

Corrections: a single-line strike-through, initials, date, and reason; never obliterate or use correction fluid on official records.

Use-of-force reports require articulation of the threat, the officer's perception, the force used, de-escalation attempts, and medical follow-up.

Records retention: NJ agencies follow the Destruction of Public Records Act and the records retention schedule; investigative records are generally retained longer than routine reports.

Supplemental reports are required when new information arises, a follow-up occurs, or a report is corrected; each is numbered and linked to the original.

Internal affairs intake: complaints are logged, classified, and investigated under the NJ Attorney General's Internal Affairs Policy and Procedures; serious complaints require immediate notification to the chief.

Documentation standard: if it is not in the report or log, it is treated as not having occurred for disciplinary and civil liability purposes.

Relevance requires probative value and materiality; relevant evidence may be excluded if probative value is substantially outweighed by unfair prejudice.

Hearsay is an out-of-court statement offered for its truth; exceptions include excited utterance, present sense impression, business records, and public records.

Chain of custody challenges go to weight, not admissibility, unless the item's identity is genuinely in doubt.

Best evidence rule requires the original writing, recording, or photograph to prove its content, unless an exception applies.

Crawford confrontation clause: testimonial hearsay from an unavailable declarant is inadmissible unless the defendant had a prior opportunity to cross-examine.

Expert testimony under N.J.R.E. 702 requires specialized knowledge, reliability of the methodology, and fit to the facts; the court acts as gatekeeper.

Testimony preparation: review reports and evidence, coordinate with the prosecutor, and avoid testifying to facts not personally observed.

Brady obligation: the prosecution must disclose exculpatory evidence; officers must preserve notes and evidence that may be discoverable.

Incident Command System (ICS): unified command, span of control (3-7, optimal 5), and common terminology; the first-arriving supervisor establishes command until relieved.

NIMS components: resource management, command and coordination, communications and information management.

Active shooter doctrine: move to the threat, isolate and neutralize, then rescue; rescue task force pairs law enforcement with EMS under force protection.

Critical incident stress: demobilization, defusing within hours, and formal CISD within 72 hours; mandatory participation is not recommended.

Evacuation vs. shelter-in-place: evacuation when the hazard is localized and routes are safe; shelter-in-place when the hazard is airborne or routes are compromised.

Emergency Operations Plan (EOP) uses ESF annexes; law enforcement typically supports ESF-13 (public safety and security).

After-action review: hot wash immediately after, formal AAR within 30-90 days, with corrective actions tracked to completion.

Mass casualty triage uses START: ambulatory first, then respirations, perfusion, and mental status; black tag for deceased or expectant.

NJ public sector labor relations are governed by the Public Employment Relations Commission (PERC); collective negotiations cover terms and conditions of employment.

Mandatory subjects of bargaining: wages, hours, and working conditions; permissive subjects may be negotiated; illegal subjects cannot.

Weingarten rights: a union employee may request representation during an investigatory interview that the employee reasonably believes may lead to discipline.

Garrity rule: statements compelled from an officer under threat of discipline cannot be used in a criminal prosecution, but can be used for administrative discipline; the officer must be advised of the choice.

Discipline must be supported by just cause: notice, reasonable rule, investigation, proof, equal treatment, and proportionate penalty.

Probationary employees have limited contractual protections; termination during probation typically requires only compliance with the contract and applicable law.

Grievance procedure: informal resolution, written grievance, step meetings, arbitration; timelines are strict and generally non-extendable absent agreement.

FMLA and NJ FLA provide job-protected leave; supervisors must track eligibility, notice, and intermittent leave documentation.

NJ Attorney General's Internal Affairs Policy and Procedures require that all complaints be accepted, documented, and investigated; anonymous complaints may be investigated at the chief's discretion.

Major discipline (suspension over 5 days, demotion, termination) requires a hearing and written findings; minor discipline follows the agency's progressive discipline schedule.

Use of force reporting is mandatory for any reportable force; failure to report is itself a disciplinary offense.

Confidentiality: internal affairs records are generally confidential; disclosure is limited to those with a need to know and as required by law.

Ethical decision framework: identify the issue, consider legal and policy requirements, consider the impact on the community and the agency, choose, and document.

Conflicts of interest: officers must disclose secondary employment and recuse from investigations involving family, friends, or financial interest.

Truthfulness is the foundational standard; a sustained finding of untruthfulness typically results in termination and placement on a Brady/Giglio disclosure list.

Early warning systems flag officers with repeated complaints, use-of-force incidents, or sick leave patterns for supervisory intervention.
