not connected?!?!?! how can you think that? if indeed there is a bomb, some joe-blow idiot is unlikely to have the resources and intelligence to plant a bomb in a building of this significance
they are reporting that there was a threat, and dogs have "reacted" to the scence, meaning the sniffing dogs are picking up traces of something that may be a bomb
let's pray this is just a sick, sick threat by some anonymous a-hole (or it could be legitimate terrorists trying to put more fear into americans, despite not really placing a bomb in the building, or it could be a decoy)
but who's to say someone won't walk into a hotel or school or train station tomorrow or the next day undetected (as you all know it is easily possible)
this just illustrates the tension that every one of us are experiencing. it is very very saddening. i know i got panicked when i saw the news a few moments ago. this has been such an impact on everyone.
