I think a pregnant woman pointing a gun at me, is a threat. I think a kid pointing a gun at me, is a threat. I think anybody pointing a gun at me, is a threat. To think otherwise, will most probably make you a statistic with a toe tag. Then the rest of us will think how foolish you were to stand there and let somebody point a gun at you.
If those targets were the aggressors and a real threat there would be a muzzle flash in those pictures. There wouldn't be a perfectly aimed weapon and a sense of hesitation.
