I seem to remember Obama making pretty blatant racial comments on a few occasions, from the Henry Louis Gates situation to going all out while discussing Trayvon. So take that bullshit elsewhere. The president isn't some dude at work, he's the chief executive of the government. You're not going to see him go all out on an issue on the edge of more violence; the protests will be bigger tonight.
I agree he should have said something more forceful about the police, comparable to what Warren or Amash said.
I will say this though: it's amazing how much Obama and democrats take the black vote for granted.
