"I was forced to shoot in self defense, officer. I'd like to speak to an attorney before I make any other statements."
That's all you say to the cops. Repeat if pressed.
BINGO!
But, why would you admit that you’re the one did the shooting? It’s unnecessary. Why not simply say, “I was violently attacked, I feared for my life and the attacker was shot.” Nothing further. The only admission then, would be the implication that you were actually present for the events in order to able to make the statement. While it sounds like you’re passing yourself off as a victim/witness, in fact you are a victim/witness, with perhaps more to say after you’ve consulted with your attorney.
