I'm still reading through posts so I don't know if you got response or not, but my local FOX News Channel (WFXS - CH.55 - Wausau) just had this as their lead story and they mentioned the plot involved the FBI building in Miami, as well as the Sears Tower.
I read that on one of the links posted on the thread- but it wasn't part of the original news flash.
Thanks for the information.
CNN is the only station still showing this.
