Bioterrorism’s and BioWatch

A Congressional report in 2003 recorded that there was concern that the BioWatch filters would fail to detect indoor or underground releases, and also that the existence of BioWatch filters in some cities would direct terrorists to attack other cities without such protection. … The Congressional Report also raises concerns as to whether BioWatch can detect pathogens in large, polluted cities, as well as issues relating to the BioWatch filter reporting harmful pathogens which are actually within safe background levels, and thus would throw up more positive hits than actual investigation warrants.
