FYI, I have a friend who has a doctorate in biochemistry. She was fairly high up in the team that sequenced the human genome.
She says that bioweapons are several orders of magnitude lower than nukes in the resources required to develop them, both as far as physical plant and finances. The primary resource is intellectual, not physical.
Give her $10M, 10000 SF of working space, a few competent assistants and she could develop an efficient bio-weapon in a few months. The scary part is that the “cost of entry” is going down all the time.
I hope she's not planning to rent in MY neighborhood!!!
