...with a now exposed ANTHRAX Link popping up in this very thread about a Payed-Off Former Admiral who's Endorsement of CLINTON in the 1992 Election got him past his Draft-Dodging past with the Voters.
Here's a secret for you - and really keep this one quiet - letter mail addressed to folks on the House and Senate side is actually examined for bombs and sometimes x-rayed for content in a separate facility long before it goes into any of those office buildings.
There, now you know the secret.
This business of "attacking a building" must also account for all the other buildings through which those letters traveled. For example there's the Brentwood facility. Maybe somebody wished to shut it down and make it's records inaccessible to investigative personnel?!?!?!?
