Saying it’s impossible for an individual to produce weapons-grade Anthrax is the same kind of flawed thinking which allowed hijacked passenger planes to be used as bombs. It’s possible, we’re likely seeing it right now.

People have been turning all sorts of thing into potentially aerosolized dust throughout history. The tools? A mortar and pestle. I’m not a biochemist, but how mechanically different can it really be to grind a clump of organic particles (spores) into dust? Harder than grinding a charred tree into dust?

In 1995, then 17 year old David Hahn built a small nuclear breeder reactor in a backyard shed. If a determined kid working fast food jobs can build a nuclear reactor with duct tape and smoke alarms, why shouldn’t a determined person be able to produce “weapons grade” anthrax without a huge factory?
