Quick reference

Power to Arrest

  • A security guard's arrest authority equals that of a private person under California Penal Code 837; guards are not peace officers.

  • A private person may arrest for a felony committed in the guard's presence, for a felony not in presence when there is reasonable ground, and for a misdemeanor committed in presence.

  • A citizen's arrest requires probable cause that the person committed the offense; suspicion alone supports only a brief investigative detention where lawful.

  • Before arrest, identify yourself and state the reason for the arrest; if the person resists, use only reasonable force.

  • After arrest, deliver the person to a peace officer without unnecessary delay and provide a statement of the facts.

  • Merchant's privilege under Penal Code 490.5 permits reasonable detention of a suspected shoplifter for a reasonable time to investigate.

  • Guards may not arrest for infractions and may not enter a private residence to arrest without consent or legal authority.

  • An unlawful detention or arrest can expose the guard and employer to civil liability for false imprisonment, battery, and civil rights violations.

Appropriate Use of Force

  • Force must be objectively reasonable under the totality of circumstances, judged from the perspective of a reasonable guard at the scene.

  • Deadly force is justified only to prevent imminent death or serious bodily injury to self or others; it is never justified solely to protect property.

  • Escalation options in order: presence, verbal direction, empty-hand control, less-lethal tools, lethal force.

  • De-escalation using time, distance, cover, and communication must be used when feasible before force is applied.

  • A guard has no duty to retreat before using reasonable force in self-defense but must not use force to retaliate or punish.

  • A guard must intervene when feasible to stop another person's excessive force and must report it.

  • After any use of force, render aid, call for medical help, notify a supervisor, and complete a written report.

  • Reasonableness factors include the severity of the crime, immediate threat, active resistance, and the number of subjects and guards.

Communication and Its Application

  • Communication has verbal (words), vocal (tone and volume), and visual (body language) components; all three should convey the same message.

  • Use open posture, visible hands, appropriate eye contact, and a calm, low tone to reduce perceived threat.

  • Active listening includes paraphrasing, asking clarifying questions, and reflecting the speaker's feelings before responding.

  • Use 'I' statements and neutral language; avoid commands like 'calm down' and avoid insulting or judgmental words.

  • Personal space zones: intimate 0 to 18 inches, personal 1.5 to 4 feet, social 4 to 12 feet, public over 12 feet; use social distance for strangers.

  • Radio traffic: identify your unit, give your location, state the nature of the incident, state what you need, then await acknowledgment.

  • Ask open-ended questions to gather facts and closed questions to confirm details.

  • Cultural and language differences may require interpreters, simple words, and patience; avoid slang and jargon.

Quick reference

Observation and Documentation

  • Report facts, not opinions: describe actions, words, and physical evidence; avoid labels such as 'suspicious' without supporting detail.

  • Include who, what, when, where, why, and how; write in first person, past tense, and chronological order.

  • Note exact times, locations, lighting, weather, and distances, plus names and contact information for witnesses.

  • Record verbatim statements in quotation marks and identify who said what.

  • Describe persons head to toe: sex, race, age, height, weight, hair, eyes, scars, tattoos, clothing, and gait.

  • Corrections: draw a single line through errors, initial and date them; never erase, white out, or rewrite a finished report.

  • Chain of custody: document each transfer of evidence, including who, what, when, where, and why.

  • Observation accuracy improves with focused attention, note-taking soon after the event, and avoiding discussion with other witnesses before writing.

Public Relations

  • A guard's professional appearance, courtesy, and calm manner create trust and reduce conflict.

  • Treat all people equally; bias, profiling, and discriminatory language create liability and damage public trust.

  • Handle complaints by listening, acknowledging, avoiding argument, making no promises, and referring the person to a supervisor.

  • Provide service such as directions, lost-person assistance, first aid, and general information.

  • Media: give no statements; refer all reporters to the supervisor or designated public information officer.

  • Explain rules and requests in a respectful, concise manner and give the person a reasonable chance to comply.

  • Build relationships with tenants, employees, and regular visitors; familiarity improves cooperation and information sharing.

Quick reference

Crowd Control

  • Identify crowd type: casual, sightseer, expressive, aggressive, or mob; the required response level rises with the threat.

  • Establish and maintain a perimeter, ingress and egress routes, and an escape path; avoid being surrounded.

  • Give clear warnings with time, routes, and consequences before dispersal; repeat the warnings and document that they were given.

  • Lawful assembly and free speech are protected; force and dispersal require unlawful conduct or imminent violence.

  • Work in teams with designated roles: contact, cover, communications, and command.

  • Use barriers and visible presence first; less-lethal tools require training and specific justification.

  • Monitor crowd mood, density, leaders, and alcohol or drug use; request additional resources early.

  • Avoid individual confrontations; separate agitators from the crowd and document identities when safe to do so.

Quick reference

Courtroom Testimony

  • Obey subpoenas; notify the supervisor, review reports, and arrive early in professional dress.

  • Swear or affirm to tell the truth; perjury is a crime and destroys credibility.

  • Answer only the question asked; do not volunteer information, guess, or argue with counsel.

  • Say 'I don't know' or 'I don't recall' rather than guessing; if you use notes to refresh memory, opposing counsel may ask to see them.

  • Speak clearly and loudly enough for the judge and jury; address the judge as 'Your Honor.'

  • Remain calm and polite under cross-examination; pause after each question and think before answering.

  • Testify to what you personally observed; distinguish facts from hearsay and opinion.

  • Know the sequence: direct examination, cross-examination, redirect examination, and recross-examination.

Quick reference

Emergency Procedures

  • Fire response uses RACE: Rescue anyone in danger, Alarm the building, Contain the fire, and Evacuate or Extinguish if safe.

  • Fire extinguisher use follows PASS: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.

  • Medical emergency: ensure scene safety, call 911, check responsiveness and breathing, start CPR or use an AED, and obtain consent if the person is conscious.

  • Earthquake: Drop, cover the head and neck, and hold on; after shaking stops, evacuate and check for injuries.

  • Bomb threat: do not touch suspicious items; note caller details, evacuate the area, and call 911.

  • Evacuation: use designated routes, proceed to the assembly area, conduct a headcount, and keep exits clear.

  • Active shooter: Run if safe, Hide if escape is impossible, Fight only as a last resort; call 911 when safe.

  • Emergency report: state what happened, the exact location, injuries, the number of people involved, and your name and callback number.
