I am sitting in my living room watching the tellie last night and today, and heard of the ricin mailing to the Republican leader. I heard him say it was ricin. I heard him describe the contents he saw as a 'white powder'. Now this thought has been bugging me all day, and I hope it develops to have a reasonable explanation: How did he know it was ricin and not anthrax? Before it was even tested he knew it was ricin. How did he know? Any information to explain this is greatly appreciated.
