History isn’t made of glass — it’ll survive a lot of clumsy handling. But a post Friday on Andrew Sullivan’s blog is simply too ham-handed with the facts to abide.

Sullivan’s been writing lately about the vanishing corner pub. A reader informing Sullivan about Chicago’s Brehon Pub posted this:

It was started in the ’80s by federal and state authorities as a sham business (under the name “the Mirage”). Its sole purpose was to catch City of Chicago building and liquor inspectors soliciting bribes from taverns. Those friendly bartenders were all FBI agents and undercover cops. A bunch of people went to jail. When the scandal was over, the place remained a bar under a new name. Not exactly the beginning you’d expect for a cozy neighborhood Irish watering hole.
