Judicial complaint about the guidelines' leniency

Though often federal judges are heard to complain that the federal sentencing guidelines are too harsh, an alien smuggling case from Florida prompted a district judge yesterday to complain that the guidelines were too lenient.  Here are the basics from press accounts (here and here) discussing the case:

Two convicted Cuban immigrants were escorted into a federal courtroom Tuesday, fully expecting a judge to put them behind bars for six years for their roles in a smuggling operation that ended in tragedy. They were wrong.

U.S. District Judge K. Michael Moore delayed his decision, saying six years was not enough punishment under federal sentencing guidelines because a young boy drowned in the Oct. 13 illegal crossing of the Florida Straits.

UPDATE:  David Markus comments on this case here at his blog, and brings up the ever-popular judge as umpire theme.
