"It is very hard for the average person to understand just how quickly a potentially deadly encounter materializes and how quickly an officer must make the decision to shoot or don't shoot. What you see very quickly, and very often not clearly, is the weapon, or appearance of a weapon, in hand. You don't typically have the opportunity to take a close look at the size of the hole in the barrel to see if it is bullet-size or BB-size. In almost all cases it is impossible to detect if the weapon is loaded or unloaded. You also don't typically have the luxury of considering the age of the person holding the weapon. The trigger will pull and the bullet will leave the gun regardless of the age of the person that pulled the trigger. ... I recognize that bad police shootings do occur and they must be dealt with accordingly. As police officers, the only thing we ask is that we be judged on what we knew, what we saw, and what we were told in the seconds just prior to the use of force — not on what was learned during the minutes and hours after the shooting."
