If there was a history of peer-reviewed scientific consensus being overturned in such a manner, I'd certainly entertain such a possibility. However, throughout post-industrialization history, since the scientific process has evolved, there hasn't been a single such occurrence. A simple application of Occam's razor and basic rationality would suggest such a scenario or "what if" with the FBI talking about how great chemtails are, is highly implausible.
Do make a post if that ever happens, and we can have a great discussion on the flaws of the scientific research on the matter.
Till that day, I'm going to consider only cold, hard evidence.
I'm sorry .. it is the CIA not the FBI..
Approx 50% of science is fraud and lies. Don't be deceived by scientific propaganda. I will write on this topic in due course.
