The future editor of the Washington Post writes:
[T]he reality is that a violent act that could be clearly traced to the rhetoric of certain leaders or groups would lead to much more damaging and coercive restrictions on political speech than anything people are considering now. Having this conversation when no one has blood on their hands is far preferable to having it when someone does.
Or, to put it another way, Fake, but true!
So people criticizing Obama better start watching what they say now, before they really do get someone killed.
