Over the weekend Mayor Daley announced that he was punishing yet another aide for yet another screwup uncovered not by his staff but by the press that he likes to blame for his political problems.

Fleet Management commissioner Michael Picardi has been sent to his room without supper—or pay—for the next three months, the mayor’s reponse to a revelation by the Sun-Times that a contractor convicted of fraud two decades ago has since received millions of dollars to fix city vehicles.

It’s the kind of swift, decisive action we’ve come to expect from the mayor when he’s presented with evidence that the public has learned about corruption and mismanagement on his watch.

As with previous scandals and embarrassments, it doesn’t mean that anything has actually been done to address the problem.
