You are the first person in fifty years to die of anthrax. That's the first person in one and a half generations, or a 1 in 371 million chance. Add to this you have some connection with one of the twenty hijackers. Say everyone has business connections with a thousand people. That's a 1 in 13,000 chance, to deal with one. Factor these two together and you have a 1 in 4.8 trillion chance of this happening to you.
Quite a coincidence!
Indeed. And as time goes by we may find out more but there is an investigation going on right now. Do you (all) really expect these agencies to hamper their own investigations by giving a "heads up" to the bad guys? This forum is not the only one instituting the "Loose lips, Sink ships" policy.
