I prize the fact that my intelligence allows me to see the point of view of both sides. I cannot determine what the actual state of mind was of this policeman, but I can say that if you do not follow the instructions of someone with an AR-15 pointed at you, and that person is law enforcement you chances are the same result will be the case.
We have the benefit of knowing that he was indeed unarmed, that the police officer did not have. Thus when he reached for his waistband to pull up his pants (assumed reason for his actions) the officer had a split second to make a choice, shot and kill him, or not shoot and possibly be shot and killed himself. I personally would never even consider being a police officer, because you are damned for sure shooting him, and may be dead if you do not.
That's why for me it is a tough call. Because I do not want to make good cops afraid to defend themselves in situations where they face real threats, nor do I want them to think they can act illegally just because they think the person is a bad person that they have in the cross hairs of their weapon.
So, to cut through the defensive blather, you believe the dead man was stupid for not following garbled orders. That’s the long and the short of it. You’re actually not all that intelligent. I detect the mind of a bureaucrat, lengthy sentences hidebound with rules and you’re quite proud of them, completely unaware of the very basic truth that you just cannot grasp.
