Bump, Old Timer.
Clearly the inert powder is almost as good as actual anthrax for causing economic disruption. every business that has a mailroom recieves checks and bills through that mailroom. one package of white powder and they are suffering economic loss. Further hazmat clean up crews use up their disposable suits and filters. It is a very effective force multiplier and while we are looking at this some other operation can be mounted.
Kudos Francis you have stated what may well be a tactic.
To those who think this is unrelated to september 11, 2001 you may well be right but I for one was unaware that the local Wal Mart stocked five gallon buckets of spores.
