Over the last 10 days in the US, since the first exposure to anthrax resulted in a death, the early anxiety expressed so freely and publicly, without any evidence whatsoever, that the country may be made a target for bioterrorist attacks, appears to have been borne out. The authorities and the media immediately attempted to link the anthrax exposure to a Florida lab in the proximity of which one of the hijackers was reported to have stayed. And since then such has been the scare that there have been daily reports of ‘white powder’ being received in the mail, although only very few have been identified as having contained anthrax spores. This growing paranoia about bioterrorism prompts numerous concerns.
