And the dirty bomb charges have disappeared without a trace or an explanation.

"Jose Padilla is sentenced to 17 years," from [1] AP:

MIAMI - Convicted terrorism conspirator Jose Padilla, once accused of plotting with al-Qaida to blow up a radioactive "dirty bomb" in a major city, was sentenced Tuesday 17 years and four months in prison on charges that don't mention those initial allegations.

The sentence imposed by U.S. District Judge Marcia Cooke marks another step in the extraordinary personal and legal odyssey for the 37-year-old Muslim convert, a U.S. citizen was held for 3 1/2 years as an enemy combatant after his 2002 arrest amid the "dirty bomb" allegations. [...]

Padilla was added in 2005 to an existing Miami terrorism support case just as the U.S. Supreme Court was considering his challenge to President Bush's decision to hold him in custody indefinitely without charge. The "dirty bomb" charges were quietly discarded and were never part of the criminal case.
