Simple, but sad. The victims were white and gay (iirc) and the killer is black. Since in this administration's own words: Blacks can't be racists against whites, there is no race card to play here. However, had the killer been white, at the very least, they would have pulled out the "hate crime" card since the vics were gay.
Again, I'm sorry Treyvon is dead, but I am incensed at the media and political spin involved with this shit. It has been there for years, no doubt, but it's blatant and unapologetic now.
