He released him from custody pending the results of a sitting grand jury. The guy could still be indicted. Or did I read the news reports incorrectly?
(Sorry, I inadvertantly sent this same comment to you via Private Mail first).
They are reporting that due to the misidentification by the FBI of a fingerprint, the court ordered the material witness proceeding dismissed. The court ordered all property seized to be returned to him. I think this guy is up to his neck in involvement with some very bad people and is connected to a Mosque they are carefully watching in the greater Portland area, but since the fingerprint was the basis of the government's case, I have a feeling this will not be going any further.
