Adrian Gibbs isn't a wild-eyed youth. He was one of the researchers whose worked was instrumental in the creation of the flu drugs Tamiflu and Relenza, and he has written or co-authored more than 250 scientific publications on viruses during his 39-year career at the Australian National University in Canberra.
The fact that Gibbs is saying that the swine flu may have escaped from a lab is causing the CDC and other health organizations to investigate his claim. They aren't buying it at this point, but they are looking into it.
