Sometimes media are asked by government officials and/or families to avoid publicizing a case because it can make the hostages into higher-value captives in the eyes of the terrorists, and that can have very serious negative consequences. In countries where ransoms are paid (not ours) it increases the price. In any case, it can result in greater security measures being taken that have the effect of making a rescue tremendously more difficult or even impossible.
I agree with many on this thread that the timing is suspicious. But since there is so much we will never know due to operational security issues, let's just be grateful for the work of Seal Team Six and for the decision by President Obama not to follow the poor precedent of Jimmy Carter in hostage matters. Even broken clocks are right twice a day.
I could accept that if their names weren't given to Reuters for publication exactly one week ago today. It's either classified for operational security or it's not.
This administration has given me no reason to trust anything it says or does. Therefore, I don't.
