One of the most effective tools I have found is to use the Observation, Orientation, Decision & Action sequence (
OODA Loop
) in reverse, as an analytical tool or system to assist in discovering “why” certain things occurred.
In conducting investigative reviews or analyses, I have learned, that as investigators we tend to miss opportunities to discover and apply valuable information, simply because the information is overlooked. The question then becomes, why do we miss it, and what is actually missing?
Recent Case
In a recent case that I was involved in as an expert, I followed my typical methodology of reviewing all evidence available regarding the case; including statements, transcriptions, video, interviews, and all data related to the initial investigation of the case. During the interview, the homicide investigators asked a very simple set of questions, all related to a core theme: “What happened?” This is all too common in nearly every case I have reviewed. The questions begin during the walk through and continue through the voluntary statements. Everyone wants to know “what happened?”, but who is asking “Why did this happen?”
In this case, the officer (Officer X) stated he arrived on a call that was dispatched as a suicidal subject, intoxicated and threatening to kill himself with an unknown weapon or means. Officer X stated that he parked his vehicle in a tactically sound location and approached the subject from the east. Officer X then stated that other officers (Officers 1 and 2) already on the scene, were yelling commands to “drop it” and to “get on the ground,” while chasing the subject into a confined courtyard in a crowded apartment complex with their duty weapons drawn.
This is what Officer X observed as he exited his vehicle and rounded the corner, X stated that he saw a glint of metal in the subject’s hand. The officer’s statement was that the subject had a knife with a colored handle in one hand and a bottle of liquor in the other. At this point, Officer X said he warned the subject he would be shot and ordered him to “get on the ground” and to “drop it.” The subject remained non-compliant and appeared to aggressively move toward the officers and shots were fired.
