So as the usual talking heads begin their “have you no decency?” routine aimed at talk radio and Republican politicians, perhaps we should turn the question around. Where is the decency in blood libel?

To paraphrase Justice Cardozo (“proof of negligence in the air, so to speak, will not do”), there is no such thing as responsibility in the air. Those who try to connect Sarah Palin and other political figures with whom they disagree to the shootings in Arizona use attacks on “rhetoric” and a “climate of hate” to obscure their own dishonesty in trying to imply responsibility where none exists. But the dishonesty remains.

To be clear, if you’re using this event to criticize the “rhetoric” of Mrs. Palin or others with whom you disagree, then you’re either: (a) asserting a connection between the “rhetoric” and the shooting, which based on evidence to date would be what we call a vicious lie; or (b) you’re not, in which case you’re just seizing on a tragedy to try to score unrelated political points, which is contemptible. Which is it?
