““Pay attention to everything going on around you. When you put your gun on in the morning, it should be like turning on the ignition key. You go into Condition Yellow. Before you enter a convenience store or a restaurant, assess the situation — don’t walk in blindly. Be aware of everything inside your twenty-one-foot personal safety zone. Watch all 360 degrees around you. Always know how to get out of where you are, whether you are on foot, in a vehicle, or in an office building or mall. Protect your back by sitting with your back to a wall. It was failure to do this that cost Wild Bill Hickok his life. Sit where you can see the exits and the cash register. In a vehicle be sure to use your mirrors. Break conventional thought patterns by ascertaining what you are really seeing. Always keep the edge. Be prepared, have a plan, and do something. “Doing something may be being the best witness you can be.””
