Patrol, Observation, and Incident Response
Purpose of patrol
Patrol exists to deter, detect, and document. A visible, unpredictable presence deters; systematic observation detects; notes and reports document. Randomness is a tactic - vary route, timing, and direction so no one can schedule around you.
Patrol fundamentals
- Systematic coverage: check doors, windows, gates, lighting, fence lines, dumpsters, stairwells, restrooms, and utility rooms; test that doors are actually locked, do not assume.
- Access control: verify badges, log visitors and vendors, challenge unescorted strangers politely and directly.
- Key control: sign out and account for every key.
- Suspicious vs. unusual: suspicious behavior fits a criminal pattern (loitering near vehicles, testing door handles); unusual behavior simply differs from the baseline and needs contact, not accusation.
Observation and description
Perception is selective - expectation fills gaps. Use a head-to-toe scan: sex, race, age, height, weight, build, hair, eyes, facial hair, scars and tattoos, clothing top to bottom, shoes, objects carried, weapons, direction of travel. For vehicles: plate, make, model, color, damage, occupants. Record details immediately; memory decays fastest in the first minutes.
Responding to an incident
- Assess - what is happening, what are the threats, who else is at risk.
- Notify - radio or call with location, nature, number of people, weapons, injuries, and what you need.
- Plan - approach with a partner using contact/cover roles; keep distance and cover; identify yourself loudly and clearly.
- Stabilize - separate, calm, render aid, hold the scene.
- Document and preserve evidence.
Radio traffic should follow the pattern: identify, location, what happened, what you need.
Worked example
On a 0200 warehouse round you find a rear fire door propped open with a brick. Reasoning: this is both a security and a life-safety finding. Do not simply close it. Clear the immediate area from a position of cover, call for a second officer, check the interior for occupancy, notify the supervisor and the client, then secure the door, log the time, and photograph the prop. The report must state who found it, the exact door, and when it was secured.
Traps that cost marks
Patterned patrols; assuming a locked door; confronting an unknown number of intruders alone; describing only clothing and not the person; failing to note the time a condition was found and corrected.
