That's what whoever sent the anthrax did.
But if they stop now, I will wonder if their object all along was to kill FBI intelligence analyst Linda Franklin -- the only victim specifically targeted -- and the other killings were cover. One of the articles yesterday said the FBI is tracking money transfers to the terrorists in this country.
Excellent point.
I half expect them to stop temporarily until they evaluate the threat of the drone. In the meantime, I figure they may pass on the duty to a cell elsewhere. I figure it may take the weekend for them to confer and set up. By Monday I expect a sniper to be active again somewhere.
