Trust your instincts when dealing with suspects
When something just doesn’t feel right — when it just doesn’t smell like it should — it’s time to heighten your awareness and start attending to those important officer safety points like maintaining distance, awareness of the hands, subject movement, deception, and the like.
A recent study of human sweat showed that humans are able to perceive fear in the sweat of others. While this has long been assumed, we now have hard evidence of the true power of one of the senses we tend to minimize in training and on the street.
Most people transmitting fear or deception indicators are simply upset with having contact with the police, however, there is always the simple truth that you may have a truly bad actor and you need to attend to all the signals being sensed. Cops that do this we tend to call “lucky” since they are always digging up stuff for the rest of us to do like transport their prisoners or inventory their seizures.
A lot of our perceptions occur at the subconscious level and are hard to bring up to our consciousness. In other words, the cause of this uneasiness or “hinkiness” is hard to explain, even to ourselves. Smell is not a dominant sense but a very potent one, so trust your intuition and gut feelings.
