I think the media is quiet because they have no further information and what information they do have they are not reporting right now. It is not about the President IMHO -- not here in Oklahoma where the media for the most part is very favorable to him.
Maybe they got burned reporting all the mis-information in New Orleans. Or maybe there is more info but they are keeping quiet to aid the investigation. If it is a terrorism, islamic or domestic, maybe there is an accomplice out there they don't want to spook.
I know...this is what is bizarre. This makes me think the Feds have a clamp-down in effect because normally reporters do not act this way.
