It's a rescue, not a release...

The use of language is important.
By way of Ace comes this example of not-quite the truth from NPR by American Barbarian

Nope no bias here. NPR reported on the “release” or “freeing” of an Australian hostage today. Their language is purposefully vague because this man was rescued by Iraqi and American forces. Let’s repeat that he was rescued by Iraqi and American forces. Certainly saying that in a report doesn’t fit NPR’s editorial point of view so they use the word “released” or “freed” so they can remain ambiguous.
