Forget Sarin. Forget any chem.

Go Bio with one tester bottle, with a heavy duty respiratory infectious agent, with say about a 48 hour incubation period, a 72 hour mild symptoms but very contagious stage, then a 12 hour death cycle.

No one would ever trace it.

One woman switching tester bottles in 3 stores in greater NYC. Disaster.

I always thought there was something sinister about those perfume ladies who greet you in department stores!

Imagine a perfume bottle in a crowded department store with ebola. In 48 hours it would have spread across the city.

Sarin is nasty stuff, you die by breaking your own back in convulsions.
