Will we ever hear the rest of this story?

So the bomb squad in Philly found a microwave with something in it, that they thought was an explosive, so they delayed and then rerouted the Philly Marathon. Turns out apparently it wasn't an explosive at all.

Now I'm wondering whether this is another ludicrous Security Theater of the Absurd Over-Reaction - like the time they shut down an airport and stopped flights all over the country because some foreign gentleman crossed a rope to kiss his wife - or possibly a hoax (stuff a microwave with something that looks like a bomb, just to freak out the Security People?), or possibly just a very, very incompetent terrorist cell ("Ismail, if this is plastique explosive that we're eating, what in Allah's name did you do with the tapioca pudding?!?!")

Here's my analysis key:
If we never hear another word about this story, it's more Security Theater of the Absurd.
If some thirteen year old gets charged with some crime that is utterly disproportionate to what actually happened, then it was a hoax.
