People are often put in challenging situations. Often times when they least expect it. They find themselves in an escalating confrontation. De-escalating people with elevated emotions can be a great hardship, especially when someone has no idea how the person(s) in question will respond or what they are capable of. Tension is high, adrenaline pumping, and you have but a single moment to decide if your life is being threatened in a fraction of a second.
This is what makes this class great as you will get different ideas and thoughts on what everyone perceives. We also talk about the law and how a fraction of a second decision can make all the difference with Use of Force.
