Trayvon Martin and Staff Sgt. Bales: Can't America Even Just Say We Were Wrong?

I was dreaming/thinking the other day that the President spoke out about Trayvon Martin

The right question is "how could this happen, why, who really did what? etc.

The wrong question might be WTF? Can't we do better than this in America in 2012? This is a terrible thing. Can't we even just say that?
