Okay. But I say he was a child acting stupidly. 12-year-olds do stupid things. Unfortunately, it led to his death. However, he had a toy that would in most instances not cause a death. As for how good a shot he was, we don’t know. I’m a pretty good shot at the range. However, I’m using two hands and carefully aiming without stress. I don’t think many people can put a round in the black at 25 feet, as you say, especially with one hand in a stressful situation. Heck, many cops can’t. You can bet the cops had a good bead on him with two hands, while the kid didn’t. That was an execution.
Relative skills after the fact are not the deciding factor on whether this was an "execution". Given what the cop saw and the potential danger of a real firearm, when the cop had been told there was a firearm, I'm okay with shooting. It's a shame the kid made bad decisions, but the cop could not bet his own life or the lives of others on the kid's innocence or ineptness. BTW, I've been to the range six times in the last week, and one-handed or two-handed I hit the black ten out of ten times (easily). My kids could all do the same at age 12.
