The danger with these symptoms occurs when they are not understood as natural, and the individual experiencing the reactions begins to process them negatively. In addition, these reactions can physically impact the individual’s desired response. In my first critical incident, an individual wielding a knife attacked me. Long before he came at me with the knife, there were signs that this incident wasn’t going to have a peaceful conclusion, and in the moments before the knife came into play, my right leg began to shake uncontrollably, making standing difficult. When I tried to request backup, I heard my voice crack. These symptoms immediately registered to me as an unacceptable level of fear, and that everyone—officers listening to the radio, and the suspect threatening me—knew that I was a coward. Negative thoughts like these can impact your actions in a way that’s very similar to when similar to when athletes get down on themselves for mistakes, and their game strategy and focus fall apart.
