Legal Foundations and Criminal Procedure

  • The Fourth Amendment protects persons, houses, papers, and effects from unreasonable searches and seizures; a warrant requires probable cause, oath or affirmation, and particular description.

  • A Terry stop requires reasonable suspicion supported by specific, articulable facts; a frisk requires separate reasonable suspicion that the person is armed and dangerous.

  • Miranda warnings are triggered by custody plus interrogation; routine booking questions and spontaneous statements generally do not require warnings.

  • The exclusionary rule suppresses evidence obtained through unreasonable searches or seizures, subject to exceptions including good faith, consent, inevitable discovery, and attenuation.

  • In North Carolina, a warrantless misdemeanor arrest generally requires that the offense occur in the officer's presence, subject to statutory exceptions such as domestic violence.

  • A search incident to lawful arrest may cover the arrestee's person and the area within immediate control; vehicle scope is limited to the passenger compartment when the arrestee is unsecured and within reaching distance or evidence of the offense is likely present.

  • Consent must be voluntary and is limited by the scope granted; the person granting consent may withdraw it at any time.

  • Chain of custody documents each transfer of evidence; unexplained gaps affect admissibility and weight.

Patrol Operations and Vehicle Stops

  • A traffic stop requires reasonable suspicion of a traffic violation or other criminal activity; the stop ends when its purpose is resolved unless new reasonable suspicion develops.

  • Position the patrol vehicle offset to the traffic lane, activate emergency lights, and notify dispatch of the stop location and plate before approaching.

  • Approach on the passenger side when practical to reduce exposure to passing traffic; maintain observation of the vehicle and occupants.

  • A high-risk vehicle stop uses backup, cover, and PA commands; occupants are controlled before officers approach the vehicle.

  • At a felony stop, one officer gives clear commands for occupants to show hands, exit one at a time, walk backward, and be restrained while other officers provide cover.

  • A vehicle inventory is conducted according to written policy and is not a search for evidence; items found in plain view during a lawful inventory may be seized if contraband.

  • Checkpoints must use neutral criteria, follow a written operational plan, and be supervised; arbitrary or pretextual stops violate reasonable suspicion requirements.

  • Directed patrol and saturation patrol concentrate resources on identified hot spots rather than random patrol.

Criminal Investigations

  • The first responder secures the scene, preserves evidence, renders aid, and limits entry; unauthorized persons contaminate the scene.

  • Photograph the scene before moving items; include overview, mid-range, and close-up images with a scale.

  • Sketches use measurements from fixed reference points; record evidence locations, dimensions, and conditions.

  • Package wet or biological evidence in paper to allow drying; avoid cross-contamination and label each item.

  • Chain of custody records every handler, date, time, and purpose; gaps can affect admissibility and weight.

  • Interview witnesses separately using open-ended questions; avoid leading questions and record exact words for admissions.

  • Eyewitness lineups should be administered blind when practicable, use fillers matching the witness description, and include unbiased instructions.

  • Digital evidence should be preserved with hash values and metadata; document capture, transfer, and storage.

Quick reference

Traffic Law and Crash Investigation

  • North Carolina's basic speed law requires speed reasonable and prudent for conditions; posted prima facie limits do not authorize unsafe speed in rain, fog, traffic, or poor visibility.

  • The NC statutory maximum is 65 mph unless a higher limit is posted on qualifying controlled-access highways; posted limits control.

  • Following too closely violates G.S. 20-152 when the driver cannot stop safely if the lead vehicle slows suddenly.

  • DWI per se in North Carolina is an alcohol concentration of 0.08 or more; commercial drivers are held to 0.04 and drivers under 21 face zero-tolerance rules.

  • Implied consent law requires a driver to submit to a chemical test after lawful arrest for DWI; refusal leads to license revocation and can be used as evidence.

  • Minimum skid speed in mph is estimated as S = sqrt(30 x d x f), where d is skid distance in feet and f is drag factor.

  • Distance traveled in feet equals 1.47 x speed in mph x time in seconds.

  • Distinguish point of impact from final rest; debris, skid marks, and vehicle damage help reconstruct the collision sequence.

Officer Safety and Use of Force

  • Graham v. Connor applies objective reasonableness under the totality of circumstances from the officer's perspective at the moment force is used.

  • Relevant force factors include the severity of the offense, immediate threat to officers or others, and active resistance or flight.

  • Deadly force is constitutionally limited to preventing imminent death or serious bodily injury; Tennessee v. Garner bars deadly force against a non-dangerous fleeing felon.

  • Officers have a duty to intervene when witnessing excessive force and to report the conduct.

  • After force is used, render aid, monitor breathing, and summon medical assistance.

  • Positional asphyxia risk increases when restraint impairs chest expansion; place the person in a recovery position and monitor breathing.

  • Cover stops bullets; concealment hides but does not stop projectiles.

  • Less-lethal tools target large muscle groups; avoid head, neck, and chest impact when practicable.

Human Relations and Community Policing

  • Procedural justice rests on voice, neutrality, respect, and trustworthy motives; perceived fairness increases compliance and cooperation.

  • The SARA model is Scanning, Analysis, Response, and Assessment for problem-solving policing.

  • Community policing combines partnerships, problem solving, and organizational transformation.

  • Bias-free policing requires decisions based on behavior and articulable facts, not race, ethnicity, religion, gender, or other protected characteristics.

  • For a mental health crisis, reduce stimuli, use calm communication, allow time, and connect the person to treatment when safe.

  • Language access requires qualified interpreters for limited-English-proficient persons; do not rely on children or bystanders for critical communication.

  • Crime Prevention Through Environmental Design uses natural surveillance, access control, and territorial reinforcement.

  • A fair complaint process includes accessible reporting, objective investigation, and notification of disposition.

Quick reference

Communications and Report Writing

  • Reports answer who, what, when, where, why, and how in chronological order.

  • Report observable facts and direct statements rather than conclusions; describe actions and conditions precisely.

  • Record exact words for admissions, threats, and statements; use quotation marks.

  • A radio broadcast identifies the unit, location, nature of the incident, and resources needed, then remains concise.

  • NCIC and other criminal justice database information is confidential and may not be released to unauthorized persons.

  • Correct paper reports with a single line through the error, initial and date it, and write the correction; do not obliterate or use correction fluid.

  • Each element of the offense should be supported by facts in the report and linked to evidence or witnesses.

  • Field notes are discoverable and should be retained according to agency policy.

Emergency Vehicle Operations and Physical Fitness

  • The three-second following rule applies in ideal conditions; increase distance at night, in rain, or when towing.

  • With ABS, apply firm continuous brake pressure and steer; do not pump the pedal.

  • Weight transfer affects steering and braking; sudden inputs reduce traction and control.

  • At intersections, scan left-right-left and clear the intersection before proceeding, even with emergency equipment activated.

  • Emergency vehicle operators may exceed normal traffic rules only when necessary and must still exercise due regard for public safety.

  • A pursuit should terminate when the risk to the public and officers outweighs the need for immediate apprehension; supervisors control and document the decision.

  • Seat belts are required for officers operating or riding in department vehicles.

  • Hydration, sleep, and conditioning support decision-making and physical performance during foot pursuits and resistance.

First Aid and Medical Response

  • Scene safety, PPE, informed consent, and activation of EMS precede patient care.

  • Adult CPR uses 30 compressions to 2 breaths at 100 to 120 per minute, with compressions 2 to 2.4 inches deep.

  • An AED should be applied as soon as available and used with minimal interruption of compressions.

  • Life-threatening limb bleeding is controlled with direct pressure and, if needed, a tourniquet 2 to 3 inches above the wound, not over a joint.

  • Shock care includes laying the patient flat, keeping the patient warm, and avoiding food or drink.

  • Opioid overdose responds to naloxone plus rescue breathing and EMS activation.

  • Stroke recognition uses BE-FAST: balance, eyes, face droop, arm weakness, speech, and time last known well.

  • Suspected spinal injury requires manual stabilization and minimal movement unless immediate danger exists.

Quick reference

Juvenile Justice and Special Populations

  • North Carolina's Raise the Age law generally treats 16- and 17-year-olds as juveniles for lower-level offenses, while serious felonies remain in adult court under transfer rules.

  • Custodial interrogation of a juvenile requires Miranda warnings plus NC-specific protections, including an opportunity for a parent or guardian to be present.

  • North Carolina law requires mandatory reporting of suspected child abuse or neglect to the Department of Social Services.

  • The ADA requires effective communication for people who are deaf or hard of hearing, including qualified interpreters for interrogations and medical consent.

  • For a person with autism, reduce sensory stimuli, use clear literal language, and avoid unnecessary touch.

  • For a person with dementia, identify yourself, reassure the person, and involve caregivers when possible.

  • Human trafficking indicators include control of movement, debt bondage, fear, isolation, and lack of identification documents.

  • Juvenile detention decisions should consider age, offense severity, risk, and available alternatives to secure custody.
