The things you mention are part of how it's supposed to work. Now, here's a dose of reality.
You, as the person who claims that the homicide you committed is justified or excused, have the burden to prove the following:
1. That you were in danger from the person who attacked you;
2. That the person was capable of carrying out a attack upon your person that could result in your death;
3. That the person
had the means to kill you, AND WAS IN A POSITION TO CARRY OUT THAT THREAT;
4. and that the person had manifested a specified intent to do so IMMEDIATELY.
So, here comes this guy. He looks at you with loathing and anger.
He starts walking in your direction. Hatred is seething from his person like a thick miasma of lethal intent. His intent is plain.
HE INTENDS TO HIT YOU!!!
Quickly, you reach under your coat to draw (insert music of choice) your ubertactical ColtGlockWesson in .95 Mankiller. As you present the weapon, demons dance around the cavernous hollowpoints in the chambers, giggling in glee at the thought of the impending carnage.
The man speeds up his pace. He raises a fist that looks to you like the hammer of Thor. You know that the time has come; talk is over.
Quickly, you center your sights, and press the trigger twice in rapid succession. The man grunts as two rounds take him center mass, and he staggers and falls to the ground. You keep the weapon trained on him, should he attampt to rise. But, a gurgling sound tells you that this confrontation is over.
Sirens sound in the distance. You stand confidently, knowing that the police will handle the situation appropriately. You have holstered your weapon, and stand there like the great citizen that you are.
Two patrol cars come up the street. They stop, both angled toward you, their lightbars flashing. You start to walk to them. But wait--what are they saying?
"LET ME SEE YOUR HANDS! STOP! PUT YOUR HANDS UP! RIGHT NOW!!"
You see that both officers have their weapons drawn. They're pointed AT YOU. Why? You were the threatened one!!
Quickly, you comply with the officer's instructions. You face about, drop to your knees, then prone. You lay there for a second--then, you feel a knee across your upper back and neck, and your arms being dragged behind you. You feel the cold kiss of steel as handcuffs are applied. As you glance upward, you stare into the chasm of the 12 gauge shotgun bore--pointed right at your head.
Your gun is taken, you are searched, and then you are dragged to your feet. The officer takes you back to her car, her partner following. After the shotgun is secured, the officer reads you the Miranda warning from a card. You agree to talk.
"So, did you shoot this guy?"
"Yes."
"Why?"
"I was in fear of my life."
"What did the guy do?"
"He raised his fist and walked toward me."
"OK. Where's his weapon?"
"He didn't have one."
A moment of silence ensues. Both officers look at you without speaking, then they glance at the dead man, who now has another group of officers standing near as a paramedic examines him.
"So, why did you shoot?"
"He was about to hit me."
The officer looks at you. She says, "But he didn't have a weapon!"
After another brief pause, she says, "Sir, you are under arrest for committing murder. Please step to the rear of my patrol unit."
If you drew and pointed your weapon at someone who was complying with no weapon visible or close at hand I suspect you would be running afoul of department procedures. If so the burden would be on you to demonstrate why that was necessary. If the suspect was a minority I suspect even more that you would be in for some serious questioning, possible disciplinary action.
If I rolled up to a scene where a person had been shot, the suspect was standing there and I did NOT put the person at gunpoint, I most assuredly WOULD be subject to disciplinary action. Race has nothing to do with it.
Sir, I must ask a question.
Of the people who have posted to this topic, I suspect that I am actually one of the LEAST qualified to expound on the subject. You see, I have only seven years in uniform.
There are people here who are retired cops; and other veterans who have been in the job a lot longer than I have.
There are others who make their living by instructing people in the methods of lawful self defense. They HAVE to be right in their teachings, or else liability would eat them alive. They MUST know the law in their jurisdictions.
And, there are people here who have actually had to make that choice--to take human life or die.
All of these people have given you advice. You still maintain that you have the right to take life under circumstances that will put you in prison, and your family in poverty for the rest of your life.
Why?
Are you seriously asking a question? Are you simply trolling?
Are you of legal age to carry firearms? Or are you a juvenile looking for information?
I've said it before, and I'll say it again.
GO TALK TO AN ATTORNEY. BETTER YET, TALK TO A PROSECUTOR IN YOUR JURISDICTION.
