The origin of the phrase “smoking gun” comes from a Sherlock Holmes story, “The Adventure of the Gloria Scott.” In Arthur Conan Doyle’s tale, an imposter posing as a ship’s chaplain commits murder. “We rushed on into the captain’s cabin . . . there he lay with his brains smeared over the chart of the Atlantic . . . while the chaplain stood with a smoking pistol in his hand at his elbow.”

Figuratively, when you have a smoking gun, there’s no need for an investigation; you know for sure the culprit is guilty. But if the chaplain had thrown the gun out the porthole just in time, Holmes would not say, “Well, there’s no smoking gun. This shall have to remain a mystery for all time. Oh, and let’s give the chaplain here the benefit of the doubt.”

I bring this up because every time there’s a new revelation about the unseemly practices of the Clintons, every time a new trough of documents or fresh disclosures come to light, scads of news outlets and Clinton spinners insist that “there’s no smoking gun” proving beyond all doubt that Hillary Clinton and the Clinton Foundation did anything wrong.
