So, in the past three days, we've had a rampage by a psychopathic cop (as Phage noted below), a school shooting and a foiled plot to enact another.
I'm wondering when the vultures will start descending on this one. The pro-gun nuts who say that if everyone carried guns, nothing like this would ever happen. The anti-gun nuts who will point to this as yet another reason to destroy every last gun in existence. The hate preachers who will say that these things happen because we don't have an explicit theocracy. The ambulance-chasers who will try to find someone to sue. The demagogues who will blame the media.
IF they already have, I haven't seen it. But I know, I absolutely fucking know, that it either has happened, or will happen.
