GARY FARBER HAS A LONG POST on bioweapons and chemical weapons as weapons of mass destruction. He disagrees with Easterbrook and with a lot of bloggers to whom he links, so I won’t bother recapping the whole discussion.
I do think that Easterbrook’s piece is in good faith, and I do think that, on the whole, chem/bio weapons are overrated in the popular mind. That’s not the same as saying that they’re not dangerous, or shouldn’t be taken seriously.
