"Bioterror research in the subway" brings to mind live virus or bacterial tests with "harmless" microbes like the tests over San Franciscon in the 1950's that may or may not have sickened (or possibly killed) residents sickened by the bacteria.
Though I wonder what testing was done to prove that the aerosol (made from wheat and corn starch, tagged with DNA) they they are spraying this time is harmless?
