Amazingly, all the public awareness and several of the people being killed did NOT seem to stop, or even slow down the rate of hold ups.
I don't remember the statistics, but I think it DID slow the rate of hold ups. At least we know those shot and killed didn't commit anymore hold ups. I guess that program was dropped when a young officer was killed. I believe it was December, 1968. The store clerk said the hijacker marched him at gun point into the storeroom where the officer was. He said the officer had stood his shotgun in the corner and was standing there with his pistol in his hand. The clerk said that he said (to the officer), "Shoot him!" The officer said (to the hijacker), "Drop your gun." And the hijacker said (to the officer), "You're kiddin!" and shot and killed the officer.
I do remember, before that time, when I was doing that job, the old lieutenant told everyone, "If you feel the need to call out to a hijacker, Police, drop your gun, you're under arrest, or whatever, you can do that, but you need to know it doesn't work the way it does in the movies. The hijacker is going to turn and shoot, so you better be ready. There's no requirement in the law to give a hijacker a warning before shooting him."
pulling the trigger while pointing at another human is HIGHLY likely to result in life changing events
Almost for certain. Many good officers leave law enforcement shortly after shooting someone, even when they were completely right in the killing. Others may stay in law enforcement, but with great changes.
Only one officer in my command shot anyone. There were numerous witnesses, including the dead man's wife, and ALL agreed that the officer had no choice but to shoot or be shot. It was a top notch young officer, friendly, always cheerful, outgoing, married to a beautiful little school teacher, had a pre-school age son. He did stay with the department, and eventually was promoted to the rank of sergeant, but he changed to a quiet, subdued personality, and was divorced.
