Any connection to the snipers by chance? (thinking of the sniper's connection to new york)
I'm considering the snipers also and the possibility of them being "runners" for the Anthrax scenario. "Hit and Run" is what they did best and I noticed a similarity in the Anthrax letters and the extortion letter (wide spacing). Sure are a lot of coincidences.
Why write an "unnecessary" note in either the case of the Anthrax letters or sniper scenario?? unless "The media is the message".
