That prosecutor is a nasty bit of rat-faced weasel, obviously trying to misrepresent reality - Kyle defended his self - better than most people ever could - amazing trigger control.
I watched a lot of it live that night and then saw many various Videos posted later. That jerk with the gun did raise his hands with the gun still being held — Kyle held his fire, and then when it seemed he wasn’t looking, the jerk, aimed the gun again, and that’s when Kyle shot his arm.
He’s lucky that Kyle didn’t put another round into his chest to totally neutralize the threat, but had he walked away instead of trying again, he’d have an undamaged arm.
And the defense is bordering on incompetence. That leaves it up to the jury.
