“The combat profiling threshold is called the Combat Rule of Three: When you observe three anomalies or indicators, you must make a decision. Do not wait for more information. Three indicators are enough information with which to act. Does this mean that you must have three anomalies to make a decision? No. In some situations, one anomaly or indicator is sufficient. For instance, following the usual rules of engagement, if an individual exhibits a hostile act or hostile intent, one indicator is enough. Someone presenting a weapon in a hostile way toward a Marine on patrol or cop on the street is all it takes to engage that individual with deadly force.”
