1918 Spanish Flu Pandemic wasn't biowarfare, Legionnaire's disease wasn't biowarfare, Black plague wasn't biowarfare.....
However, from now on it will be completely impossible to convince anyone that WANTS to believe a newly emergent contagious disease is biowarfare, that it isn't. So I'm not even going to try.
People absolutely hate the idea of anything significant or bad happening in the world without it having a specific human cause; they HATE randomness or the appearance of randomness more than anything.
China is a classic area for a naturally occuring contagious disease to emerge or jump species and people were worried about that happening naturally long before people were really concerned about biowarfare.
This did not emerge in China. And the history of the outbreak (now four days) points strongly at a release. It's also too late to contain - it has hit the whole world already. That plane is just one of many. There's two interesting factors now - the mortality rate, and can a treatment be found.
So many folks are unaware of the fact that microscopic "bugs" always have and always will enjoy propagating as much as humans do, with or without terrorists.
Wrong, check your facts.
