They just don't know when to stop. Guantanamo prosecutors wanted a sentence of 30 years to life for Salim Hamdan, Osama bin Laden's driver. A military jury gave him 5 1/2 years, 5 years of which he's already served. The prosecutors should have taken that slap in the face gracefully. Instead, they asked the military judge to reassemble the jury to resentence Hamdan. They argued that the judge should not have instructed the jury that Hamdan would receive credit for time served because the judge has no authority to award that credit to an enemy combatant.

The prosecutors want the five years and one month Hamdan has already served to be "dead time" -- time a prisoner spends in custody that never gets credited to any sentence. They wanted to argue to the jury that Hamdan should serve an additional 5 1/2 years. But the jury already decided that Hamdan should be done with his sentence at the end of the year. There's no reason to put him in jeopardy of a longer sentence. The presiding judge appropriately denied the prosecution's latest shameful effort to save face.
