Okay, she gets a pass
I understand the point of her segment and race was not mentioned in this one. The fact that she did not mention race is far more important that showing the picture for 26 seconds.
The opportunity is lost forever as to whether I would have noticed that it was a black guy in the background picture while she was speaking of something else. It is a moot point since the emphasis is on the weapons and not race. I agree that he is easily identifiable as black for anyone paying attention.
