It now shows that the whole incident happen in just 8 minutes, they engaged around 8:40 AM and the shooter was down at 8:48 AM. As in most ambushes, the shooter or aggressors chose the time and place most effective for them. The other big factor is the aggressor(s) has already decided to engage, the Policeman, has to determine if it is a shooting situation. This always gives the edge to the aggressor, perhaps only a split second, ,but that's the edge the aggressor needs to get off the first shots.
