What do you think about this comparison floating around on Facebook?

I can’t link to the photo, but it is explained very easily. It’s a picture of Trayvon Martin and James Homes. The caption reads, “They were so busy looking for the kid in the hoodie that they missed the clown in the red hair with the machine gun.” What do you think of the whole thing? I am reserving my opinion on it for now, and have not commented to my friend yet how I feel about it. I want to know the collective’s reaction and see the ways you guys take it to mean.

If it matters, this was posted by a black friend of mine.
