Calvin Klein's Ricin?
A Saudi Arabian student going through security at a Philly airport sprays himself and security workers with cologne to prove the bottle he is carrying is, in fact, cologne. All hell soon breaks loose. FBI, hazmat teams, quarantine—the whole package.
The mistake the guy made, of course, was assuming his spritzing would prove his bottle contained only cologne. Contained areas like airports and airplanes are great places to spread noxious agents. And in an age of suicide attacks, spraying oneself proves nothing.
But there has got to be a better way to handle such missteps besides the DEFCON 4 response. A table-side cologne test kit or something.
For record, the bottle contained Diesel Green. And if he'd spritzed me with it, I woulda Tasered his ass just on principle.
