Let's say you're the President and you've been told there are 15 devices really to go off. One each day. Five have been found and neutralized, one is found and dumped at sea. Do you tell people about it the incident? Do you tell them that that there are 9 more devices out there and you're frantically looking for them? Talk about panic sex!
where is the evidence that anyone is "frantically" looking for them?
Those are tough questions to answer. Short answer is yes, and ask for the public's help. Call me crazy, but I beleive in Truth. Oh well. . .
