I think it’s a lot more valid to use Trayvon’s image as a target than say, DHS using pregnant women, old men, old women, and children (all white as well) to desensitize their DHS and the like agents to fire on all kinds of white US citizens.
They want to talk racism, let’s talk racism.
When I first read that story I felt the same way. Desensitizing seems the reason. Can’t think of any other.
