Who Should We Blame for the Anticlimactic Balloon Boy Saga?

After a thrilling chase sequence, Balloon Boy was found...to have never been in the balloon in the first place. We're glad he's safe, but now the question comes: Who's to blame for this whole catastrophe?

Stevie Safran cleverly notes in Twitter that "Balloon Boy's parents say he won't be grounded, fail to recognize ironic choice of words." But somebody's gotta be punished for this, right? All kinds of public servants (EMTs, FAA, police) came out, on the taxpayer's dime, for something that turned out to be totally unnecessary. So who's to blame?
