I work at Johns Hopkins. Since last week, our Security office has logged over 115 calls reporting suspicious white powder: no stuff leaking from envelopes or packages, or even a baggie full of powder: just white powder, like powdered sugar, Cremora, paper dust, cleaner, etc found in bathroom stalls, near copiers and coffee machines, on countertops.
Guess what? The terrorists are winning because our feminized, sue-happy society has everyone thinking irrationally and worried about covering their butts.
