The Swine Flu Conspiracy

Okay,

I apologize for the attention grabbing title, but hear me out.

I just think it's strange that this flu has no less than four "parts" in it:

1. An European swine, an Asian Swine, a human and avian.  This is just odd.

2. It attacks primarily the 20 - 40 year olds. Just like SARS and just like Spanish fle

Possible explanations for the origin:

A. Entirely natural occurrence, This is wat virusses and flu does, simply human interaction on a global scale caused this to mutate so bizarrely. It might've been speeded by pollution or gen manipulation, but that's about it. ==> NO HUMAN INTERFERENCE

B. a Lab experiment gone wrong. They were researching a CURE , but it somehow got loose in the open through incompetence. Remember that vaccins are nothing but weakened forms of the virus itself.==> UNINTENTIONAL but well meant HUMAN INTERFERENCE

C. Lab experiment gone wrong. Someone was researching how to make a bioweapon, but it got loose by accident.==> UNINTENTIONAL SINISTER HUMAN INTERFERENCE

D. Someone IS experimenting with bioweapons and used the Mexicans as guinea pigs. ==> FULLY INTENTIONAL SINISTER HUMAN INTERFERENCE. This explains the age group thing, if you want a weapionized flu, you wouldn't want something that only attacks babies and oldsters.

 So, what I'm looking for is reasons why A. is true, and B and C and D, are completely false ...

The only reason why A could be true is the "awww, they wouldn't do that" approach. Which we also said about lots of other things ....
