I Am Legend: Fact or Fiction?

[Mookage]

Well, if you think about it, scientists can't put something to large scale use until it has been throughly tested. So I think that as long as nobody in the scientific community slacks off and doesn't do their tests we should be okay from a large, man made epidemic. But never rule out the fact that someone could be in a rush one day and not do their experiment properly.

If one link of the chain isn't perfect, the chain will fall apart (the chain being the human race).
