Stevens worked for the tabloid The Sun; perhaps he and some of his co-workers were trying to see how easy it would be to get ahold of anthrax. Ever since 9/11 the media have been tripping over each other trying to show the public just how unprotected we are in airports, from chemical/biological attacks, etc. Perhaps The Sun cooked up a scheme to acquire anthrax and write and expose and it backfired horribly on them.
Just a thought; flame on.........
