So, I kind of hate to do it, but I think I must agree with Dick Cheney.
There is no moral equivalence between ISIS and Ferguson.
Sure, one is a violent, narrowly theocratic group who kills civilian hostages in a particularly provocative and cruel way. But we would be remiss in not remembering that those hostages are at least from a country who invaded the group's homeland, bombed and destroyed it, causing the death of hundreds of thousands, and then placed into power an equally narrowly theocratic bunch on the other side of the divide. This is a war.
In Ferguson, the killing was done by the local police - the ones with the mandate to protect the one who was killed.
You're right, Dick. They aren't morally equivalent at all.
(Of course, Obama didn't really say there was a moral equivalence; he merely pointed out what other nations such as Russia love to point out on their own: "at times we too have failed to live up to our ideals; that America has plenty of problems within our own borders... yes, we have our own racial and ethnic tensions." "This is true," he said. And it is.)
