Richard Spertzel: There are some people, and I don't... I can't name names because I don't know anybody in that way, that would be against using animals in research even if it didn't do anything to them. And so they just simply refuse to do it. In which case, you know, they're in the wrong pursuit of a career. But I don't really see that that changes that much. You know, I mean, you know, if the work really needs to be done, then you may only have one animal model for that work. You have no choice, unless you're going to forget it. And, you know, there're still rumblings about smallpox around the world, you know, and if you wanted to get into smallpox studies, you're probably going to end up with the great apes. And you know, you don't really have an alternative. You can't... You know, man is a great ape, but you can't go to man for... so... And I don't know anybody who's doing that, I'm just using that as an example. I think the ethical decision is in the very beginning, upfront. You know, you don't want to... you know, if the ethics of it bothers you, then you're in the wrong occupation. And then the question is does that work need to be done, or not be done, and to be facetious, that's above my pay-grade. There's plenty of accusations by... I don't know... got to choose my words carefully... by people who are opposed to science, are opposed to studies. These are the ones that don't want you doing anything whatsoever that's going to affect an animal, be it a bird, or a rodent, whatever. And... yeah. That's a problem. But they're not in, doing the work. They're not the ones that you would hire to do the work.
