Freeze: The Initial Instinct<\/h2>\n<p>The freeze response is the first stage of the threat response. When someone perceives danger, such as making visual or audible recognition of the sudden presence of law enforcement in proximity to their own position, they may instinctively freeze. This is an unconscious attempt to avoid detection and assess the threat. This is an honest reaction, as the human threat response leaps into action before the person can decide if the perceived threat is credible or not. The freeze response can take shape both physically and verbally, as it is displayed by someone reacting to police presence.<\/p>\n<p><strong>Observable behaviors:<\/strong><\/p>\n<ul>\n<li>Sudden stillness or cessation of movement when noticing police.<\/li>\n<li>Fixated gaze; a change in posture from one that is relaxed and\u00a0open\u00a0to one that is of low confidence, with the shoulders up, chin tucked, and head down, consistent with trying to hide\u00a0<strong>in<\/strong>\u00a0plain sight.<\/li>\n<li>Holding an unnatural posture, such as tensing up or &#8220;locking in place.&#8221; The &#8220;deer in headlights&#8221; look will commonly be observed at this time as well.<\/li>\n<li>While operating a motor vehicle or other form of transportation, the person rapidly brakes,\u00a0decreases\u00a0speed, or stops\u00a0altogether.<\/li>\n<\/ul>\n<p><strong>Proactive policing insight:<\/strong>\u00a0Officers on patrol should be trained to recognize this initial moment of hesitation or unnatural stillness as a potential indicator of stress or guilt. While a freeze response doesn&#8217;t confirm criminal behavior, it can be a preliminary cue to dig deeper, giving us the confidence to then attempt to find a lawful violation to conduct a stop of the person operating a vehicle, bicycle, or\u00a0traveling\u00a0on foot.<\/p>\n<h2>2. Flight: The Urge to Escape by Physically Distancing<\/h2>\n<p>If the freeze phase doesn&#8217;t de-escalate the perceived threat, or in other words, achieve the desired effect, the next instinctual response is flight. This can manifest as an attempt to physically escape, or more subtly, as behavioral avoidance, such as changing direction when spotting officers, physically creating distance between the officer and\u00a0oneself, and\/**or putting\u00a0physical\u00a0buffers or barriers between their position and police. These behaviors show themselves as the person\u00a0reacting and making\u00a0physical efforts to\u00a0avoid\u00a0being apprehended by police.<\/p>\n<p><strong>Observable behaviors:<\/strong><\/p>\n<ul>\n<li>Sudden or unprovoked movement away from officers or patrol units. Depending on\u00a0whether\u00a0the person is on foot, in a vehicle, on a bicycle, or\u00a0using another\u00a0mode of transportation, this movement away from the officer, commonly referred to as <a href=\"https:\/\/portal.bluetogold.com\/the-moment-of-visual-recognition-understanding-nonverbal-distancing-behaviors-in-proactive-policing\/\">distancing behavior<\/a>, can take on a\u00a0variety\u00a0of different appearances, but\u00a0ultimately, the goal is always\u00a0the\u00a0same: get as far away, as fast as possible, from the officer, without looking too obvious. Simply put, a good starting point for an officer looking for potential suspects is to watch who begins to distance\u00a0themselves\u00a0upon their presence. If in a vehicle, who is taking rapid turns away? Who is switching lanes, even when it is unsafe to do so or there is an unsafe gap to\u00a0fit\u00a0into between vehicles\u00a0at\u00a0that moment? Who changes direction now that an officer has come into their view? Who pulls into the parking lot you are in, not having previously seen you sitting there, but now that they have, leaves entirely without conducting any legitimate business? These are questions you need to ask yourself as you conduct patrol.<\/li>\n<li>Pre-flight indicators:\u00a0adjusting clothing (e.g., waistband checks), tightening backpacks, tying\u00a0shoelaces, stretching out, nervous glances toward exits, alleyways, or areas of cover.<\/li>\n<li>Attempting to leave an area quickly after noticing police.<\/li>\n<\/ul>\n<h2>3. Fight: The Defensive Aggression<\/h2>\n<p>When escape seems impossible or when the individual feels cornered, the final threat response, fight, kicks in. This response is particularly dangerous and unpredictable. It can range from verbal hostility to full physical assault.<\/p>\n<p><strong>Observable behaviors:<\/strong><\/p>\n<ul>\n<li>Clenched fists, jaw tightening, or sudden changes in voice tone.<\/li>\n<li>Rapid breathing, pacing, or squared shoulders (a pre-attack indicator).<\/li>\n<li>Reaching toward the waistband or pockets, a common sign of arming or bluffing.<\/li>\n<li>Refusing commands with increasing agitation.<\/li>\n<li>Streamlining, the suspect begins shedding items from around their face, head, and\/or neck such as a lanyard, necklace, pair of sunglasses, hat, earrings, etc.<\/li>\n<li>Nasal wing dilation\/nostrils flaring, as the body oxygenates, preparing for physical action.<\/li>\n<li>Verbally attacking the officer, making accusations of racism, harassment, illegal policing, threats of\u00a0lawsuits, getting them fired, or other\u00a0tactics.<\/li>\n<li>Repeatedly attacking the validity and basis for the stop.<\/li>\n<\/ul>\n<p><strong>Proactive policing insight:<\/strong>\u00a0Recognizing the precursors to aggression allows officers to either de-escalate or tactically reposition to ensure safety. Training should emphasize reading nonverbal cues, using verbal de-escalation techniques, and understanding the link between fight responses and perceived loss of control.<\/p>\n<h2>Final Thoughts<\/h2>\n<p>The human threat response system is universal, but how individuals manifest freeze, flight, and fight can vary based on context, past experiences, and intent. For law enforcement officers, the value lies in recognizing the patterns of behavior that suggest someone may be reacting not just to fear, but to the presence of authority due to guilt or criminal intent.\u00a0These\u00a0physical\u00a0reactions, as they unfold in real-time, are honest reactions. These responses give an officer a focus point to then continue\u00a0observing\u00a0and\u00a0determine, as they get closer to the person and begin following from a distance,\u00a0whether\u00a0more behaviors show themselves. These behaviors will show themselves at all levels of criminal activity, from someone driving while suspended or with a minor traffic warrant, all the way\u00a0to\u00a0someone who\u00a0has\u00a0just committed an armed robbery or homicide. It is the job of the police officer to observe the reaction, find a lawful basis for the stop such as a traffic offense or city ordinance violation to\u00a0conduct\u00a0a stop, and then once stopped, investigate to\u00a0determine\u00a0what level they are dealing with.<\/p>\n<p>By sharpening awareness of these instinctual behaviors and incorporating them into proactive policing techniques, officers can enhance both officer safety and public safety, while improving the effectiveness of patrol-based crime detection.<\/p>\n<h2>Related from Blue to Gold<\/h2>\n<ul>\n<li><a href=\"https:\/\/portal.bluetogold.com\/act-natural\/\">Act Natural<\/a><\/li>\n<li><a href=\"https:\/\/portal.bluetogold.com\/the-limbic-system-deep-dive-how-does-this-relate-to-successful-proactive-policing\/\">The Limbic System Deep Dive: How Does This Relate to Successful Proactive Policing?<\/a><\/li>\n<li><a href=\"https:\/\/portal.bluetogold.com\/tell-tale-tension-pre-flight-indicators-and-behavioral-cues-of-criminals-for-police\/\">Tell-Tale Tension: Pre-Flight Indicators and Behavioral Cues of Criminals for Police<\/a><\/li>\n<\/ul>\n<p><em>This article is legal training, not legal advice.
