On May 5, 1995, a Cleaning Woman in Japan Happened

On May 5, 1995, a cleaning woman in Japan happened to notice a couple of plastic bags sitting beside the toilet in a men's restroom in one of the busiest subway stations in Tokyo. The woman picked up the bags and put them by the door to dispose of later. What she didn't realize is that the bags contained a sophisticated chemical weapon that, if properly activated, would have the potential to produce enough cyanide gas to kill 10,000 people. Instead, the unidentified woman disrupted the trigger mechanism, starting a small fire that was put out before the cyanide gas could be produced. What drawback to the use of chemical weapons to commit bioterrorism does this story demonstrate?

A) Chemical weapons act too slowly, which may permit people to get help.
B) These types of bioterrorist weapons are easily recognizable, and can be easily neutralized even by untrained staff.
C) Because of the high level of skill required to build and transport, there are rarely an option for most terrorists.
D) Unlike bombs, the volatility in bioterrorist weapons causes them to be more likely to fail or detonate at the wrong time.
